If f(x) = -7x+5x^2+10, what does f(-2) equal?
2 answers:
f(x) = -7x + 5x² + 10
f(-2) This means that x is -2, so you plug in -2 for "x" in the equation
f(x) = -7x + 5x² + 10
f(-2) = -7(-2) + 5(-2)² + 10
f(-2) = 14 + 5(4) + 10
f(-2) = 20 + 24
f(-2) = 44
-7x+5x^2+10 f(-2) given
-7(-2)+5(-2)^2+10 plug in -2 where you see X
14+5(4)+10 do (-2)^2
14+20+10 multiply 5(4)
45 add your numbers (this is the final)

18= +5+x
x=3
If you do 3•5, you get 15.
Then do 3+15, you get 18.
