Answer:

If f(x) = -(-2x - 5), then f(-5) is equal to -5

Solution:

Given that the function is f(x) = -(-2x – 5)

We are asked to find the value of f(-5)

Finding value of f(-5):

The value of f(-5) can be found by substituting -5 in place of “x” in the given function f(x) = -(-2x – 5)

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

For f(x) = f(-5),

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

f(-5)= -(10-5)

f(-5)= -5

The value of the above given function f(x)= -(-2x-5) for x= -5 i.e., f(-5) is -5
