Question

Graph the following function on a coordinate graph.take a number (x), quadruple it , and subtract 2.

Answer 1

First, we have to write the function in the form:

y= mx+b

take a number x. quadruple it (multiply by 4) and subtract 2:

4x-2

So, the function is:

y=4x-2

The graph crosses the y-axis at y=-2 ( y-intercept) and has a slope of 4
