Simplify the expression f (x + h). f(ath) = f (x + h) - f(z) Simplify the difference quotient, h f (ath) - f(2) Rationalize the numerator in the difference quotient. (If applies, simplify again.) f (ath) - f(2) h The derivative of the function at a is the limit of the difference quotient as h approaches zero. f'(x) =lim f(z th) - f(2) h -+0 h Submit Question1 Suppose that f is a function given as f (a) - -3x - 1 Simplify the expression f (x + h). f ( x t h ) = Simplify the difference quotient, f (x th) - f (z) h f (x th) - f(2) h The derivative of the function at a is the limit of the difference quotient as h approaches zero. f'(2) =lim f(x th) -f(z) h- 0 h Submit Question\fQuestion 15 Compute each of the following limits.
