The correct option is,

⇒ The graph crosses the x-axis at x = -2 and x = 1 and touches the x-axis at x = 0.

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given function is,

f(x) = x⁴ + x³ - 2x²

Now, We can simplify as;

f(x) = x⁴ + x³ - 2x²

    = x²(x² + x - 2)

    = x²(x² + 2x - x - 2)

    = x²[x(x + 2) - 1(x + 2)]

    = x²(x + 2)(x - 1)

So the factored form of the polynomial function is,

f(x) = x²(x + 2)(x - 1)

For x - intercepts,

F(x) = x²(x + 2)(x - 1) = 0

x = -2, 1

This function has even multiplicity = 2 at x = 0.

Therefore, graph of the function will touch the x-axis at x = 0

And at other roots x = -2, 1 has odd multiplicity = 1, so the graph will cross the x-axis.

Thus, Option (3) will be the correct option.

Answer: C. The graph crosses the x-axis at x=-2 and x=1 & touches the x-axis at x=0

Step-by-step explanation:

You can tell this by factoring the equation to get the zeros. To start, pull out the greatest common factor.

f(x) = x^4 + x^3 - 2x^2

Since each term has at least x^2, we can factor it out.

f(x) = x^2(x^2 + x - 2)

Now we can factor the inside by looking for factors of the constant, which is 2, that add up to the coefficient of x. 2 and -1 both add up to 1 and multiply to -2. So, we place these two numbers in parenthesis with an x.

f(x) = x^2(x + 2)(x - 1)

Now we can also separate the x^2 into 2 x's.

f(x) = (x)(x)(x + 2)(x - 1)

To find the zeros, we need to set them all equal to 0

x = 0

x = 0

x + 2 = 0

x = -2

x - 1 = 0

x = 1

Since there are two 0's, we know the graph just touches there. Since there are 1 of the other two numbers, we know that it crosses there.

-4x + 7 = 11 help me please!

Answers

-4x + 7 = 11 

First, subtract 7 from both sides. / Your problem should look like: -4x = 11 - 7
Second, subtract 11 - 7. / Your problem should look like: -4x = 4
Third, divide both sides by -4. / Your problem should look like: x =   (4)/(-4)
Fourth, change the fraction to a negative. / Your problem should look like: x =  -(4)/(4)
Fifth, cancel 4 out. / Your problem should look like: x = -1

Answer: x = -1

you want to get "x" by its self.

-4x+7=11    (subtract 7 on both sides)
-4x=4           (divide -4 on both sides)
x=-1

What Fraction Is Bigger 8/15 or 14/25?

Answers

The first thing to do is to make the denominators the same: 
  8/15 = 40/75
14/25 = 42/75

42/75 is bigger than 40/75.  Therefore, 14/25 is bigger than 8/15. 
In order to solve these problems, you would have to change the fractions so that they have equal denominators. In order to do so, you must find the LCM of the denominators, in this case 15 and 25.

The LCM is 75 for these two numbers. Now, you change the fractions based on their new denominators.

8/15 = 40/75
14/25 = 42/75

I got this by dividing 75 by the previous denominators and multiplying that result by the original numerators. (i.e. 75/25 = 3 * 14 = 42)

So, now that you've changed both fractions to have equal denominators, you can see, by the numerators, which of the two is bigger.

Your answer is 14/25.

Hope this is clear and helps you out for future problems :)
