Question

If f(x)=-x-4, evaluate f(-3)

Answer 1

f(-3) = -1

Explanation:

Given the linear function, f(x) = -x - 4:

We must substitute the value of the input, x = -3, into the function:

f(x) = -x - 4

f(-3) = -(-3) - 4

f(-3) = 3 - 4

f(-3) = -1

Therefore, the corresponding output of the function, given its input value of x = - 3 is: f(-3) = -1.
