Question

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

Answer 1

Answer:

$y = - 2x + 6$

Step-by-step 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:

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