Question

What is f[g(3)] for the following function? f(x) = 4x2 − 3 g(x) = 5x − 2

Answer 1

Answer:

673

Explanation:

• f(x) = 4(x)² − 3

• g(x) = 5(x) − 2

solve:

• f[g(3)]

• f(5(3) − 2)

• f(13)

• 4(13)² − 3

• 673

Answer 2

Step-by-step explanation:

f[g(3)] = ?

When f(x) = 4x² - 3

g(x) = 5x - 2

f[g(3)] = ?

where g(3) => 5(3) - 2 => 13

f(13) = ?

where f(x) = 4x² - 3

f(13) = 4(13)² - 3

f(13) = 676 - 3 => 673

f[g(3)] = 673
