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
1.) 3+2=? ?=5 brothers 2.) 54+9=? ?=63 students 3.) 15-9=? ?=4
4.) 60-20=? ?=40 children 5.) 50-15=? ?=35 trees 6.) 14+4=? ?=18 times
Don't know why you needed help with this but ok.
Both solutions:
x = -1, -7/3
