Answer:
1. y= |x| -15
2. y = -|x| +3
Step-by-step explanation
.The V shape means absolute value (the | | ), since its upside down, the equation has to be negative. The tip of the V doesn't start at 0 like normal, it's up 3, so the equation has a +3 at the end. The x intercept at (3, 0) is just so you can check your work. If we plug in 3 for x, we do in fact get 0 for y.
Not sure, if correct but here.
Turning points or how many dips it has
hmm
1st degree is a line, no turning points
2nd degree is parabola, 1 turning point
3rd degree has 2,
etc
xdegree has x-1 turning points
7th degree has 7-1=6 turning points
