Question 21

The student is presented with the domain and range of a function f(x), as well as two given values of the function. -40 and f(1)=-13
f(-10)=-40
Select each statement that must be false about f(x) in the corresponding box.

a) f(-12)=-20

b) f(0)=0

c) f(5)=-40

d) f(-30)=-30

f) f(-25)=-10

e) f(1)= 13

Answer 1

e) f(1)= 13

Explanation:

The problem statement tells us f(1) = -13. A function can only have one value for f(1). That value is not 13, so f(1) = 13 is false.
