Question

Consider the function f(x)= 4x+ 6 Determine the output produced by the input value

x= -2.

Output: f(-2)=

Answer 1

-2

Explanation:

All functions have one output per input.

Inputs and Outputs

In a function, the input is the value you plug in and the output is the resulting value. Since this is a function, each input will only have one output. Inputs are the x-values of a function, and outputs are the y-values are a function. So, to find the output, we need to plug the input in for x and solve.

Finding the Output

To find the output, we need to plug -2 in for x.

• f(-2) = 4(-2) + 6
• f(-2) = -2

This means that the output for -2 is -2. So, one of the coordinate points for this function is (-2, -2). Remember, that the outputs are y's and the inputs are x's.
