The output of a function is 8 more than 3 times the input. What is the equation?

The input is the independent variable, usually denoted by x. The output is the dependent variable, typically denoted y.

More than indicates addition, times is multiplication, and in this context is indicates equals.

Thus y=8+3x  or y=3x+8.

The output of a function is 8 more than 3 times the input.

Lets call the output y and in the input x. 

The output (y) is equal ( = ) to 8 more than ( + 8) 3 times the input (3x). 

Put this together : 

y = 3x + 8

 function is 8 more than 3 times the input.

x is the input

3 times means multiplications so 3x

Having 8 more means you are adding 8 so your function will be

3x+8=y
