What is the curve : y= -2x
2 answers:
The curve is a linear equation.
<h3>What type of curve is the given equation?</h3>
It is actually a linear equation, meaning that this is a straight line, not a an actual "curve".
To view the "shape" of the curve, you need to graph it.
You could use a program or do it by hand, to do it by hand, you need to evaluate a lot of points of the equation, and then graph them to see the general behavior of the equation.
In this case, I graphed it with a program, and in the image, you can see that this is a linear equation that decreases as the variable increases.

You can see that the function is constantly equal to 3 if x is less than -2 (included). So, we have
if [/tex] x\leq -2[/tex]
Similarly, the function is constantly 1 if x is less than -2 (excluded). So, we have
if [/tex] x> -2[/tex]
