Question

If f(x)=2x-3,find f(-2)

Answer 1

The answer is -7, 2(-2) is -4. Then - 3 is -7

Answer 2

f(-2) = -7

Explanation:

To find the answer, you simply need to substitute -2 into f(x). Like this,

f(-2) = 2(-2) - 3

Then, you must simply solve the rest of the equation.

f(-2) = -4 - 3

f(-2) = -7

That is how you find the answer.
