Accepted Solution
A:
f(x) sine curve with points at 0, 0 and pi over 2, 4 and pi, 0 and 3 pi over 2, negative 4 and 2 pi,0
g(x) x y 0 0 pi over 2 2 π 0 3 pi over 2 −2 2π 0
h(x) = 2 sin x + 3 Which function has the greatest rate of change on the interval from x = 0 to x = pi over 2
The change of f(x) from 0 to π/2 is 4 The change of g(x) from 0 to π/2 is 2 We can rule out g(x).
As for h(x): h(0) = 2 sin(0) + 3 = 3 h(π/2) = 2(sin(π/2)) + 3 = 2 + 3 = 5 Change of h(x) from 0 to π/2 is 2.
Greatest change between 0 and π/2 is found with f(x)
