Question

need to check the problem on the attachment because I got 7/2

Answer 1

did anyone get the same answer

Answer 2

f(x) = 4/3x^(3/2) -2 x^(1/2)
f'(x) = 4/3 * 3/2 (x)^(1/2) -2 * 1/2 (x)^ -(1/2)
f'(x) = 2(x^ (1/2) ) - x^(-1/2)
f'(4) = 2*(square root (4) ) - 1/square root of 4) = 2*2 - 1/2 =4-1/2 = 3/2

Answer 3

no 4-1/2=7/2

Answer 4

\[\frac{8}{2}-\frac{1}{2}=\frac{7}{2}\]

Answer 5

Sorry 4 -1/2 is 7/2 right
Typing error there

Answer 6

no prob! I was just worry for a few minutes
