(1 point) Let f(x) = 3x - 2x + 9. Then according to the definition of derivative f'(x) = lim (Your answer above and the next few answers below will involve the variables x and h. We are using h instead of Ax because it is easier to type) We can cancel the common factor from the numerator and denominator leaving the polynomial Taking the limit of this expression gives us f'(x) = -4x+3
Thank you. - Part 1: Limit of a difference quotient Suppose f(x) = – 5. Evaluate the limit by using algebra to simplify the difference quotient (in first answer box) and then evaluating the limit (in the second answer box). X - 2 (f(5 + h) – f(5) lim h0 Him ( 15 + ) - 109 ) = lim ( = lim h0 | Part 2: Interpreting the limit of a difference quotient - Part 1: The derivative at...
