F(x)= -2x^2 - 5 and f(2)= -13

can someone solve this in steps please?

This is one way you could write out the steps

f(x) = -2x^2 - 5

f(2) = -2(2)^2 - 5

f(2) = -2(4) - 5

f(2) = -8 - 5

f(2) = -13

Step-by-step explanation:

First you have to get the meaning clear.

f(2) means that wherever you see an x on the right side of the equation, you put a 2.

f(2) means -2*(-2)^2 - 5

(-2)^2 = -2 * -2 = 4

f(2) = -2 * 4 - 5

f(2) = - 8 - 5

f(2) = -13

answer: .64
