<h2>
1. y-intercept</h2>
The quadratic function 
represents a parabola. In fact, the graph of a quadratic function is a special type of U-shaped curve called a parabola. To find the y intercept, we set 
as follows:
<h2>
2. x-intercepts</h2>
To find the other x-intercept, we must set 
as follows:
Therefore, the other x-intercept is 
. You can see both the y-intercept and the x-intercepts in the figure below.
Answer:
8x + 80
Step-by-step explanation:
positive side
Answer:
To find the volume, we must find the area of the circle and multiply it by its height, think of a cylinder as an object made up of MANY circles. So, V=pir^2h... so diameter is 6cm so radius = 3cm...
therefore, Volume = (pi)(3^2)(12) = 108(pi)
where 12 = height 3 = radius
For the surface area, we need to find the area of the 2 circles(top and bottom ) so once again,
2(pi)(r^2) = 2(pi)(9)
for the area of the rectangle(if we unfold the cylindrical can) we get D(pi)(12) where D= Diameter
so the surface area is
SA = (2)(9)(pi) + 6(pi)(12)
SA = 18pi + 72pi = 90pi
