Question

a mapping (Look at #6 to see whating" is). (4 pts)14. Evaluate the expression below if: (3 pts)a = -8, b= 17, and c = 21a? -(b + c)5 6-7, determine if it's a function.(1 pt)

Answer 1

a^2 -(b + c)

a = -8

b = 17

c = 21

(-8)^2 - (17 + 21)

64 - (38)

64 - 38

26

It is a function because the shape of the graph must be a parabolla

Vertical parabollas are functions.
