given f(x) = 5x - 3, find f (-1).
My answer:
f(-1)= 5(-1)-3
= -5-3
= -8
correct
Yes, your answer is correct. To find f(-1), you substituted -1 into the function f(x) = 5x - 3.
By replacing x with -1, the expression becomes:
f(-1) = 5(-1) - 3
Then, you simplified the expression:
f(-1) = -5 - 3
And finally, you performed the subtraction:
f(-1) = -8
