Question

Interpret the intercepts for each situation. Use the intercepts to graph the function.

Answer 1

It's a linear function: y = mx + b.

The graph of the linear function is a straight line. Two points are enough for plotting a graph of this function.

The domain of this function is

`D=[0,\ \infty)`

We have the function: y= 3x - 6

We choose any two x and calculate the value of y:

for x = 0 → y = 3(0) - 6 = 0 - 6 = -6 → (0, -6)

for x = 2 → y = 3(2) - 6 = 6 - 6 = 0 → (2, 0)
