Xy=18
y=2x
y = 18/x
y = y
2x = 18/x
2x(x) = 18(1)
2x^2 = 18
x^2 = 18/2
x^2 = 9
so x = square root of 9 = 3
x = 3.

Given the function ƒ(x ) = 3x + 1, evaluate ƒ(a + 1).

Setler79 [48]

Answer:

$\Huge \boxed{3a+4}$

Step-by-step explanation:

The function is given.

$f(x)=3x+1$

To find : $f(a+1)$

The input for the function f(x) is (a + 1).

Replace x with (a + 1).

$f(a+1)=3(a+1)+1$

Expand brackets.

$f(a+1)=3a+3+1$

Simplifying.

$f(a+1)=3a+4$
