find h'(2) given that f(2) = 3, g(2) = 4, f'(2)= 2 and g'(2)= 7.
A. h(x) = 5f(x)  4g(x)
B. h(x) = f(x)g(x)
C. h(x) = f(x)/g(x)
D. h(x) = g(x)/ 1+ f(x)

Joshie,
simply chart it out.
f(x) g(x) f'(x) g'(x)
2 3 4 2 7
then plug them into the equations.
A. (5)3  4(4)
15  16 = 31
B. (3)4 = 12
C. 3/4
D. 4/13
= 4/2 = 2

Joshie,
well the chart didn show up right but when x = 2 then
f(x) = 3
g(x) = 4
f'(x) = 2
g'(x) = 7
then plug them into the equations.
A. (5)3  4(4)
15  16 = 31
B. (3)4 = 12
C. 3/4
D. 4/13
= 4/2 = 2
