What is the value of h (-7)

h (x) = |3x| - 1

20

Step-by-step explanation:

h (-7) just means that inside the x value, you replace the x with a - 7.

h (-7) = |3x| - 1

h (-7) = | 3 (-7) | - 1

h (-7) = | - 21 | - 1

NOTE: - 21 is inside |x|, those straight lines mean absolute value. No matter what, any negative number would turn into a positive one. And if it's posititve, then it stays positive.

h (-7) = 21 - 1

h (-7) = 20
