Question

The range for the function f(x) = 4x-6 is y < 0.

Which set contains all values of the domain satisfying this function?
O A. x < 1.5
OB. X>0
O c. x > 1.5
O D. x < 0

Answer 1

Since y = f(x), and they're making y < 0, this means f(x) < 0

f(x) = 4x-6

f(x) < 0

4x-6 < 0

4x < 6

x < 6/4

x < 3/2

x < 1.5

The inequality sign stays the same the entire time. It flips only when we multiply or divide both sides by a negative number.

Final Answer: Choice A
