Given the relation y = –4x2 – 8, if the input is 2, what is the output? 8
–8
–16
–24

- 24

Step-by-step explanation:

Given

y = - 4x² - 8

The input is the value of x and the output the corresponding value of y.

Here input is 2 , substitute x = 2 into the relation, that is

y = - 4(2)² - 8 = - 4(4) - 8 = - 16 - 8 = - 24

For an input of 2, the output is - 24

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
