Can someone help me solve this problem: f(x)=-x^3+x^2+x, find f(-2)
Is it a -6

Well, let's see.....
Substitute -2 for x:
f(x) = -x<SUP>3</SUP> + x<SUP>2</SUP> + x
f(-2) = -(-2)<SUP>3</SUP> + (-2)<SUP>2</SUP> + (-2)
Now, do the arithmetic. Remember to follow the order of operations; do the powers first:
f(-2) = -(-8) + 4 + (-2)
Next, find the value of -(-8):
f(-2) = 8 + 4 + (-2)
And finish by doing the additions......
f(-2) = 10
I hope this helps you.
