Evaluate a Function
Evaluate the function at the given value of the independent variable and simplify.
-$$g ( x ) = 3 x + 1 ; \quad g ( x + 1 )$$
A) $3 x + 4$
B) $3 x + 1$
C) $3 x - 1$
D) $\frac { 1 } { 3 } x + 1$

Question

Quizplus · Accepted Answer

To evaluate the function at x + 1, we simply substitute x + 1 in place of x in the function:
g(x + 1) = 3(x + 1) + 1
= 3x + 3 + 1
= 3x + 4
Therefore, the answer is A, 3x + 4.

Evaluate a Function Evaluate the Function at the Given Value g(x)=3x+1;g(x+1)g ( x ) = 3 x + 1 ; \quad g ( x + 1 )g(x)=3x+1;g(x+1)
