need 2 and 3 ; no decimal answers

Suppose . f( - 7) = - 8 and f'( - 7) = 10 * g( - 7) = 5 and g'( - 7) = 9 . h( - 7) = - 7 and h'( - 7) = - 5. 1. The derivative of 8/(z) +99(=) at - 7 is equal to h(z) 2. The derivative of sin(#(8f(x) + 9g(z))) at - 7 is equal to 3. The derivative of tan(#f(x))h(x) at - 7 is equal to Question Help: Written Example Submit
