Final answer:
To find the quantity f(x + h) - f(x) all over h, substitute the given function into the expression and simplify.
Step-by-step explanation:
To find the quantity f(x + h) - f(x) all over h, we substitute the given function into the expression:
f(x + h) = 4(x + h)² + 3(x + h) - 5
f(x) = 4x² + 3x - 5
Substituting these values into the expression f(x + h) - f(x) all over h, we simplify:
4(x + h)² + 3(x + h) - 5 - (4x² + 3x - 5) all over h
Simplifying further will give you the answer.
