Question

4. Graph the following a: f(x)=4x-4 is what I need help with.

Answer 1

Step-by-step explanation:

it is a line (as the variable x is only occurring with the exponent 1, this makes this a linear equation or simply a line).

all we need to do is find 2 points, mark them in the graph, and the draw a line through both points (and beyond these points).

the first point for me is always for x = 0.

f(0) = 4×0 - 4 = -4

so, the first point is (0, -4)

and for a second point let's pick e.g. x = 2

f(2) = 4×2 - 4 = 4

so, this second point is (2, 4).
