Answer:
- the graph does not cross the x-axis
- the solutions are x = -8, x = 4.
Step-by-step explanation:
The given equation graphs as two points on the number line:
- x = -8
- x = 4
_____
In order for the graph of a function of x to cross the x-axis, there must be a function of x. The given equation is an equation that is true only for specific values of x. <em>It is not a function of x</em>.
If you want to graph y = x^2 +4x -32, you will find it crosses the x-axis 2 times.
___
<em>About the attachment</em>
The blue line is a graph of the left side of the given equation. It crosses the x-axis 1 time. The green curve is a graph of the right side of the given equation. It crosses the x-axis 2 times, in different places than the blue line. The x-values of the points where the blue and green curves intersect are the solutions to the equation.
The red curve is the proposed function of x (above). It crosses the x-axis 2 times.
