Question

which of the following represents a range of the function f(x)=-4x+1 for the domain -5,-1,0,2,10

Answer 1

a. (-39,-7,1,5,21)
b.(-41,-9,1,5,21)
c.(-19,-3,1,5,21)
d.(-41,-9,-3,-19)

Answer 2

range is all the y values and domain is all the x values.

f(x) = -4x + 1
f(-5) = -4(-5) + 1
f(-5) = 20 + 1
f(-5) = 21

f(-1) = -4(-1) + 1
f(-1) = 4 + 1 = 5

f(0) = -4(0) + 1
f(0) = 1

f(2) = -4(2) + 1
f(2) = -8 + 1
f(2) = - 7

f(10) = -4(10) + 1
f(10) = -40 + 1
f(10) = -39

so we have : -39,-7,1,5,21
