Substitute -1 for x. Simplify.
If f(x) = 4x-3, find the following. f(-1)
To find f(-1), we substitute -1 for x in the function f(x) = 4x - 3.
So, let's substitute -1 for x:
f(-1) = 4(-1) - 3
Now, simplify the expression:
f(-1) = -4 - 3
f(-1) = -7
Therefore, when we substitute -1 for x in the function f(x) = 4x - 3, the value of f(-1) is -7.
