given f(x) = x^3 - 3, find f(-2).
I got f(-2) = -11. Can someone please check if I'm right?
correct
f(x) = x^3 - 3
f(-2) = (-2)^3 - 3
= -8 - 3
= -11
OMG I CAN'T BELIEVE I GOT IT RIGHT!!!! YAY, THANKS SO MUCH :')
To find the value of f(-2), we can simply substitute -2 into the function f(x) = x^3 - 3 and evaluate it.
So, plugging in -2 for x, we have:
f(-2) = (-2)^3 - 3
Now let's simplify this expression step by step:
f(-2) = (-2)(-2)(-2) - 3
= -8 - 3
= -11
Therefore, you are correct! The value of f(-2) is indeed -11. Well done!
