Answer:
x = 0, 9
Step-by-step explanation:
To find our roots, set the binomial factors equal to zero:
x = 0
x - 9 = 0
x = 9
50 x 18 not that hard actually :) 900

Answer:
No
Step-by-step explanation:
The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular X value. The Y value of a point where a vertical line intersects a graph represents an output for that input X value. If we can draw any vertical line (left to right) that intersects a graph more than once, then the graph does not define a function because that X value has more than one output. A function has only one output (X) value for each input value.
EXAMPLES:
(3,-7), (2,4), (-3,-7), (3,0), (0,2)
The first numberin each set is th X value or output.
The 3 has two Y values, -7 and 0, it can only have one Y value.
Only one X can have a one Y vale to make it a function.
