Answer:
Step-by-step explanation:
1) y = 50x + 2500
2) y = 200x + 1000
if we build a system with the two equations, we have:
50x+2500 = 200x + 1000
150x = 1500
x = 10
y = 2000 + 1000 = 3000
3) 10
4) $3000
Zeros are
Write in factor form and solve
- (x-0)(x-(-3))(x-(-4))=0
- x(x+3)(x+4)=0
- x[x(x+4)+3(x+4)]=0
- x(x²+4x+3x+12)=0
- x(x²+7x+12)=0
- x³+7x²+12x=0
Points given (-2,16)
Solve for n
On solving we get
So the function is
- y=-4(x³+7x²+12x)
- y=-4x³-28x²-48x
