Question

Consider functions f and g.

f(x)=3 √x + 1

x g(x)
1 --------> 0
2 --------> 1
3 --------> 4
4 --------> 9

What is the value of f(g(1))?

A) 3√2+1
B) 9
C) 0
D) 1

Answer 1

• D) 1

Explanation:

Given functions f and g

• f(x) = 3 √x + 1
• g(x) given as table

To find

• f(g(1))

Solution

As per table

• g(1) = 0

So

• f(g(1)) = f(0) = 3√0 + 1 = 0 + 1 = 1
• f(g(1)) = 1

Correct option is D) 1
