Answer:
1. 20
2. 23
3. 6
Step-by-step explanation:
We have that:
f(x) = 2x
g(x) = x² + 1
f(g(x)) is the composite function of f and g. So
f(g(x)) = f(x²-1) = 2(x²+1) = 2x² + 2
1. f(g(3))
f(g(x)) = 2x² - 2 = 2(3)² + 2 = 18 + 2 = 20
2. f(3)+g(4)
f(3) = 2(3) = 6
g(4) = 4² + 1 = 17
f(3) + g(4) = 6 + 17 = 23
3. f(5) - 2g(1)
f(5) = 2(5) = 10
g(1) = (1)² + 1 = 2
f(5) - 2g(1) = 10 - 2*2 = 10 - 4 = 6

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>
The ratio of boys and girls =3:5
Let
Number of boys=3x
Number of girls =5x
- According to the question Numbers of girls=130
- Now interchange both sides and get x
<h3>Now </h3>
The number of boys=3x
=3×26=78
Number of boys is 78.

The statement which describes what the equation tells is; The number of customers they have prior/before the review is; 500 customers.
- The number of customers they have 2 months after the review is; 222.22 customers.
<h3>Exponential functions</h3>
According to the given function;
- The intercept of the function represents the number of customers the restaurant has prior to the review.
This means the number of customers they have prior/before the review (at m=0) is; 500 customers.
Additionally, after 2 months of the review;
C = 222.22 customers
