Let f(x)= x - 1 and g(x)=x² + 5.
Find (fog)(4)
Then (fog)(4)=(Simplify your answer.)

20

Step-by-step explanation:

f(x)= x - 1 and g(x)=x² + 5

(fog)(x)

=f(g(x))

=f(x^2+5)

=x^2+5-1

=x^2+4

(fog)(4)

=4^4+4

=20

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
