Answer:
f(-5)=-5
Step-by-step explanation:
f(-5)= -((-2)(-5)-5)
= -(10-5)
= -(5)
= -5
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
