Question

Select the correct answer. What is the standard form of this function? f(x) = -(x − 4)2 + 2

Answer 1

choice D

Explanation:

first extend
`(x-4)^(2)` which equal to
`x^2-8x+16`

secondly distribute the negative sign
`-(x^2-8x+16) = -x^2+8x-16`

after that add like terms which are -16+2

so final answer is
`-x^2+8x-14`

Answer 2

d

Explanation:

The standard form of a linear equation is Ax+By=C.
