For the photo it is question number 4.

if f(x) =2^x +4 and g(x) =1/2x^3 the value of f(5) +g(-2) is

 Choice (3):  "32" .  The answer is : 32 .


Explanation:


If f(x) = 2ˣ +4 and g(x) = (1/2)x³ ; the value of f(5) + g(-2) is: ?

Find f(5):   f(5) = 2⁵ + 4 = 36 ;

Find g(-2):  g(-2) = (1/2) * (-2)³ = (1/2) * (-8) = -4 ;

  f(5) + g(-2) = 36 + (-4) = 36 − 4 = 32.

The answer is:  32 ; which is:  Answer choice: "3" ; in the figure.
