Answer by mastermath(14) (Show Source):
You can put this solution on YOUR website! f(x)=2x^2-7x+3
(a) f(2)
answer: -3
show your work here:
To find f(2), substitute 2 in place of x
f(2)=2(2)^2-7(2)+3
f(2)=2(4)-14+3
f(2)=8-14+3
f(2)=-3
------------------------------------------
(b) f(-3)
answer: 42
show your work here:
To find f(-3), substitute -3 in place of x
f(-3)=2(-3)^2-7(-3)+3
f(-3)=2(9)+21+3
f(-3)=18+21+3
f(-3)=42
