Question

13. What is h( 2/3 )? 17 points Use /(x) = - 3*+ 11, 8(x) = 22-7x, and h(x) = 15 - 9x1 to evaluate each function.

Answer 1

h(x) = l15 - 9xl

h(2/3)

We have to replace the value x=2/3 in the function:

h(2/3)= l 15 - 9(2/3) l

h(2/3)= l 15 - 18/3 l

h(2/3)= l 15- 6 l

h (2/3)= l 9 l

h(2/3)= 9
