Answer:
(a) 3 - 2x - 2x² (b) -21
Step-by-step explanation:
given, y +2x² = 3 -2x
make y the subject:
y = 3 - 2x - 2x²
if y = f(x)
then
f(x) = 3 - 2x - 2x²
(b)<u> to find f(3) we need to replace x with 3:</u>
<u />
3 - 2(3) - 2*(3)²
-21
42
(125/3 = 41.6..., 41.6... rounded is 42)
I decided to do mental math and figured out it was -12. but you can cross multiply since both answers have to equal one another. you will still get the answer.
