Answer 1

Answer: The correct answer for the question that is being presented above is this one: "The range of the function is all real numbers; The function has two x-intercepts. The statements about the graph of the function f(x) = 2x2 – x – 6 that are true includes: The range of the function is all real numbers; The function has two x-intercepts.

Answer 2

Answer:

we have

$f(x) = 2x^(2) -x-6$

using a graphing tool

see the attached figure

This is a quadratic equation (vertical parabola) open up

The vertex is a minimum---------> Vertex $(0.25,-6.125)$

The domain of the function is all real numbers-------> interval (-∞,∞)

The range of the function is the interval----------> [-6.125,∞)

The function has two x-intercepts-----> $(-1.5,0)$ and $(2,0)$

The function is increasing over the interval-----> (0.25,∞)

The function is decreasing over the interval-----> (-∞,0.25)

Consider the function represented by the equation 6c = 2p – 10. Write the equation in function notation, where c is the independent variable.

Answers

we have

$6c = 2p - 10$

If c is the independent variable

then

p is the dependent variable

clear variable p

$6c = 2p - 10$

Divide by $2$ both sides

$3c = p - 5$

Adds $5$ both sides

$3c+5 = p - 5 +5$

$p=3c+5$

Write the equation in function notation

$f(c)=3c+5$

therefore

the answer is

the equation in function notation is equal to $f(c)=3c+5$

f(c)=3c+5 is the right answer

1200+0.075x>=3300 what is the solution to the inequality

Answers

Solving inequalities is just like solving any other Algebraic problem...look to P.E.M.D.A.S. (Parenthesis, Exponents, Division, Addition, Subtraction). So lets take a look at this problem now.

1200 + 0.075x $\geq$ 3300

Subtract 1200 from both sides...
0.075x $\geq$ 2100

Now divide by 0.075...
x $\geq$ 28000

NOTE: If you divide or multiple by a negative number while solving inequalities, you must flip the sign. Ex: You answer would be x $\leq$ 28000 if you would've multiplied or divided by a negative.
