Answer:

160

Step-by-step explanation:

Plug in 6 for r, and 8 for s in the expression:

(r)(s) + (14)(s) = (6)(8) + (14)(8)

Remember to follow PEMDAS. First, multiply, then add:

(6 * 8) + (14 * 8)

48 + 112

112 + 48 = 160

160 is your answer.

Let f(x)=3x+1 and g(x)=2x2−1 Find f(g(2)) 10 22 97 28

kupik [55]

Answer:

f(g(2)) = 22

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Composition of functions

Step-by-step explanation:

Step 1: Define

f(x) = 3x + 1

g(x) = 2x² - 1

Step 2: Find g(2)

Substitute: g(2) = 2(2)² - 1
Evaluate: g(2) = 2(4) - 1
Multiply: g(2) = 8 - 1
Subtract: g(2) = 7

Step 3: Find f(g(2))

Define: g(2) = 7
Rewrite: f(7)
Substitute: f(7) = 3(7) + 1
Multiply: f(7) = 21 + 1
Add: f(7) = 22

And we have our final answer!
