Fx = x ^ 2 + 9找出fx + h
Given that f (x) = 3x 2 + 2x, find f (x + h). This one feels wrong, because it's asking me to plug something that involves x in for the original x . But this evaluation works exactly like all the others; namely, everywhere that the original formula has an " x ", I will now plug in an " x + h ". [4xh - 2h^2 - h]/h = 4x - 2h -1 Note that if you take the limit of this expression as h goes to zero, you get 4x - 1, which is the first derivative of the original function. You would take exactly the same approach in 2), but you need to be very careful with the fractions. Use la forma de vértice, y=a(x−h)2+k y = a ( x - h ) 2 + k para determinar los valores de a a , h h , y k k . a=1 a = 1. h=0 h = 0. k=−9 k = - 9.
