To graph y=∣5x∣ using a table of values, we will assign some random values for x and calculate the corresponding values for y. Recall that the absolute value removes the negative sign.
x | ∣5x∣ | y=∣5x∣ |
---|---|---|
-4 | ∣5(-4)∣ | 20 |
-2 | ∣5(-2)∣ | 10 |
0 | ∣5(0)∣ | 0 |
2 | ∣5(2)∣ | 10 |
4 | ∣5(4)∣ | 20 |
Now we can plot and connect the obtained points on a coordinate plane. Keep in mind that the graph of an absolute value function has a V
shape!
