Put x = 2 in f(x) you'll get,f(2) = 2(3) x 2 = 12. so next point could be ( 2,12)
y= x^2 - 6x-7
Vertex = -b /2a
b= -6
a= 1
-(-6)/2(1)= 3
x= 3
Use the substitution method to find y
y= (3)^2-6(3)-7
(3)(3)-18-7
9-25
y= -16
Vertex is (3, 16)
Find x- intercept (y= 0)
y= x^2 - 6x-7
(x-7)(x+1)
x-7= 0
Move -7 to the other side. Sign changes from -7 to 7
x-7+7= 0+7
x= 7
x+1= 0
Move +1 to the other side. Sign changes from +1 to -1
x+1-1= 0-1
x= -1
Answer :B. Vertex: (3, -16); Intercepts: x=-1,7
okay so first you wanna turn that 120% into a decimal and the decimal form of that would be 1.2 or 1.20
Secondly you want to multiply 875 by the 1.2
875*1.2 = 1050
So if they sell 120% of last years sales they will sell 1050 cars this year.
Hope this helped :)
