Question

Please help! Use the quadratic function to predict y if x equals 6. Y=2x^2-2x-2

A) y= -58
B) y= 58
C) y=-60
D) y= 60

Answer 1

b) y=58 you follow the instructions

Answer 2

The correct option is B.

Explanation:

The given quadratic function is

`y=2x^2-2x-2`

We have to find the value of the function y at x=6.

Substitute x=6 in the given function.

`y=2(6)^2-2(6)-2`

`y=2(36)-12-2`

`y=72-14`

`y=58`

The value of the function is 58 at x=6 is 58.

Therefore the correct option is B.
