Question

Find the zero (s) of the function f (x) (x-1) 2-9. Enter your answer in the first response box. If there is more than one correct answer, enter your other answer in the second response box.

Answer 1

Answer - - - - > x=4 ^ x=-2

When they ask you about the zeros of the function you set "y" as zero and then...

`(x - 4) ^(2) - 9 = 0`

`x {}^(2) - 2x + 1 + 9 = 0 \\ x { }^(2) - 2x - 8 = 0 \\ (x - 4)(x + 2) = 0 \\ x = 4 \\ x - 2`
