Problema Solution
What is the range of the function f(x) 3.2x for the domain {-4 -2 0 2 4}?
Answer provided by our tutors
The function is:
f(x) = 3.2x
Since the domain is the set {-4, -2, 0, 2, 4} we plug each value for x and find the range:
f(-4) = 3.2*(-4)
f(-4) = -12.8
f(-2) = 3.2*(-2)
f(-2) = -6.4
f(0) = 3.2*0
f(0) = 0
f(2) = 3.2*2
f(2) = 6.4
f(4) = 3.2*4
f(4) = 12.8
The range is {-12.8, -6.4, 0, 6.4, 12.8}.
