Question

Write the quadratic function f(x) = (3-x)2 in standard form.

Answer 1

`y = - 2x + 6`

Explanation:

`since \: f(x) = y \\`

then the equation reads:

`y = (3 - x)2 \\ y = 6 - 2x \\`

The standard form of an quadratic function is:

`y = mx + c \\`

So the answer is:

`y = mx + c \\ y = - 2x + 6`
