Rewrite f(x) = –2(x − 3)2 + 2 from vertex form to standard form.

f(x) = –2x2 − 18
f(x) = –2x2 + 12x + 20
f(x) = –2x2 + 12x − 16
f(x) = 4x2 − 24x + 38

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
