Plug in points to general form of quadratic function:
y=ax²+bx+c
(0,7)
7 = c
(2,13)
13 = 4a +2b + c
(4,3)
3 = 16a + 4b + c
Now solve the system of equations in two unknowns.
Substitute the value of 7 for c in the second equation:
13 = 4a + 2b + 7
6 = 4a + 2b
3 = 2a + b
b = 3 - 2a
Substitute this into third equation:
3 = 16a + 4(3-2a) + 7
3 = 16a + 12 - 8a + 7
3 = 8a + 19
-16 = 8a
a = -2
b = 3-2a = 3 - 2(-2) = 7
a = -2, b =7. c = 7
The quadratic function is y= -2x² + 7x +7
Answer:
4
Step-by-step explanation:
Because both equations =1x, they can be set equal to each other. This means it can be written as 12=3x. To find the answers you must divide both sides by 3 to get x by itself. This makes the answer x=4
