Ineed with this one too if anyone can show me step by step

D) 2x^2 + 11x^3 + 12x^2 - 10x - 8

Step-by-step explanation:

you multiply each term of the first expression with each term of the second expression and add all the terms

so start with x^2 * 2x^2 = 2x^4

x^2 * 3x = 3x^3

x^2 * -4 = -4x^2

4x * 2x^2 = 8x^3

at this point it's clear that the correct answer is D but we can continue

4x * 3x = 12x^2

4x * -4 = -16x

4x^2

6x

-8

by adding

2x^2 + 11x^3 + 12x^2 - 10x - 8

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
