Answer:
a=1
Step-by-step explanation:
y=ax^2+bx+c
y=x^2+x-20
b=1
c=-20
20
If you work this out you get 1:
5/100*20
5 divided by 100 is 0.05 then 0.05 times 20 is 1
x-int: (3, 0)
y-int: (0, -1.5)
x-intercept is the x-value when y = 0
y-intercept is the y-value when x = 0
Step 1: Find x-intercept
0 = (x - 3)/2
0 = x - 3
x = 3
(3, 0)
Step 2: Find y-intercept
y = (0 - 3)/2
y = -3/2
(0, -1.5)
