Let f(x) = x2 and g(x) = x + 5. write an expression that represents each composition:
a. g(f(4))
b. f(g(4))
c. (f ∘ g)(x)

(a) 21

(b) 81

(c)                  

Step-by-step explanation:

We have given the function

(a) We have to write the expression for given composition

Now first we find f(4)

So f(4) =

So

(b)

Now first we find g(4)

So g(4) =

So

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

the answer is 3/2 and for decimal: 1.5
