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.

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

The length of a rectangle is represented by x, the width is represented by 6x^2-4x-2. What is the area of the rectangle?

navik [9.2K]

Answer:

$2x(3x^2-2x-1)$

Step-by-step explanation:

Area of a rectangle is simply length times width

{ $6x^2-4x-2$ } * x would be the area

That can be simplified to

$6x^3-4x^2-2x$

Which can be further simplified to

$2x(3x^2-2x-1)$
