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).
Using the point on the graph (4, 1) solve for a
1 = a(4-3)² - 1
2 = a
Answer:
2z + 4 = 8
Z = 2
Step-by-step explanation:
2z + 4 = 8
-4. -4
2z = 8
—- —
2. 2
z. =. 4
Easy Peasy! Hope this helped :) have great day!!
You want to find the ratio of BC to AB. You know that the length of BC is 16 and AB is 20. So, it is 16:20. However, you want to find the simplest form so find the greatest common factor of 16 and 20 which is 4. Divide both by 4 to get 4:5.
