Question

10.

Use the quadratic function to predict y if x equals 6.

y = 2x2 − 2x − 2

A. y = 60

B. y = 58

C. y = −60

D. y = −58

Answer 1

B. y = 58

Explanation:

b) y=58 you follow the instructions

...............................................................................................................................................

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.
