Answer: domain: x>-3
range: y > -1
Step-by-step explanation:
Answer:
D is the solution
Step-by-step explanation:
1.25 = 1.25/100= 125%
1 1/4= 1 25/100 = 1.25
125%= 125/100= 1.25 and 1 1/4
x-intercepts are points of the form (x, 0), and y-intercepts are points of the form (0, y).
You find the x-intercepts by solving for x such that y = f(x) = 0:

You know x - 6 is a factor of f(x), which means x = 6 is a solution to the above equation, and that means that (6, 0) is one x-intercept.
You can find the other two by dividing f(x) by x - 6 (i.e. further factorizing f(x)).

So we have

and this means the x-intercepts are (6, 0), (2, 0) and (1, 0).
The y-intercept is easier to find; set x = 0, then solve for y = f(0):

and so the y-intercept is (0, -12).
Multiply the -3 by what is inside the parentheses.
-3y + 15 =24
subtract 15 from both sides.
-3y=9
divide by -3 on both sides.
y = -3
