Question

If f(x)=3x+2 and g(x)=x²-x, find each value
A. g(3b)
B. f(2)+1

Answer 1

To find g(3b), substitute the value of x = 3b into the function g(x). To find f(2) + 1, substitute the value of x = 2 into the function f(x) and simplify. Simplifying the expression gives: f(2) + 1 = 6 + 2 + 1 = 9.

Step-by-step explanation:

To find the value of g(3b), we need to substitute the value of x = 3b into the function g(x) = x² - x. Plugging in the value, we get:

g(3b) = (3b)² - (3b)

Simplifying the expression gives:

g(3b) = 9b² - 3b

To find the value of f(2) + 1, we need to substitute the value of x = 2 into the function f(x) = 3x + 2. Plugging in the value, we get:

f(2) + 1 = 3(2) + 2 + 1

Simplifying the expression gives:

f(2) + 1 = 6 + 2 + 1 = 9
