What is the domain of the function? Question 2 options: - 1

Answers

Answer 1
Answer:

Answer:

"all real numbers"

Step-by-step explanation:

The domain is the set of x-values for which the function is defined.

Domain is also the input of the function (graph).

The graph shown has arrows in both directions. It means that the graph goes on in both directions. If we were to think correctly, we would say the graph would go on-and-on in both +ve x and -ve x directions. So there would be values of x for all real numbers (going to infinity and negative infinity)

Hence, the domain is all real number, the last answer choice is right.

The value of the given expression will be equal to -3.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The solution to the expression is:-

=  4(  x  +  3  ) (  x + 1  )  /  (  x  +  5  )  (  x  -  5  )

=  4(  3 +  3  ) (  3  + 1  )  /  (  3  +  5  )  (  3  -  5  )

=  (  4  x  6  x  4 )  /  (  8  x   -2  )

=  -3

Therefore the value of the given expression will be equal to -3.

Suppose a parabola has vertex (-3, 7) and also passes through the point (-2, 11). Write the equation of the parabola in vertex form.​

Answers

Answer:

f(x)=4(x-(-3))+7

Step-by-step explanation:

vertex form= f(x)=a(x-h)^2 +k

vertex= (h,k)

x=-2

f(x)=11

plug in all the variables

11=a(-2-(-3))^2 +7

simplify the right side

11=a(1)^2+7

11=a+7

subtract 7

4=a

equation= f(x)=4(x-(-3))+7
