<span>Hi, A cylinder has 3 faces - 2 circle ones and a rectangle</span>
Find f(-2) f(x)=9x^2-5x+2
f(-2) means replace x in the equation with -2:
f(-2)=9(-2)^2-5(-2)+2
= 9(4) +10 + 2
= 36 +10 + 2
= 48
f(-2) = 48
Setup the equation from the words as follows:
√
3x/5
=x
Simplify this to:
0=x(5x−3)
Since we are toldx≠0,x=3/5.
