Question

which is the greatest value in the range of y= -4x + 15 for the domain {-3, -1, 0, 2}
a) 23
b) 27
c) 15
d) 19
e) 31

Answer 1

Answer:

greatest value of y = -4x+15

put x = -3

-4(-3)+15 = 12+15= 27

put x = -1

-4(-1)+15= 4+15= 19

put x = 0

-4(0)+15= 0+15= 15

put x = 2

-4(2)+15= -8+15= 7

highest value is 27.
