Question

Given f ( x) = − 5 + 2 f(x)=−5x+2,find f ( − 4 )

Answer 1

f(-4) = 22

Explanation:

To find f(-4) for the given function f(x) = -5x + 2 , you simply need to substitute x = -4 into the function and perform the calculation:

f(-4) = -5(-4) + 2

Now, multiply -5 by -4:

f(-4) = 20 + 2

Finally, add 20 and 2:

f(-4) = 22

So, f(-4) = 22
