What you should know for this case is that all quadratic functions represent a parabola.
We have then that the function with vertice (-2, 0) is:
y = (x-2) ^ 2
Notice that if you substitute the value x = -2 in the equation then y = 0
Answer:
y = (x-2) ^ 2

Answer:
okay I need help please
Step-by-step explanation:
find cos b in the triangle
The answer is 31.4. I hope this helps.
Use 2 points on the line to find the slope.
Slope = change in y / change in x
The two points used: (-2,5) and ( 1,-10)
slope = (-10 -5) /(1- -2) = -15/3 = -5
the y intercept is where the line is at in the y direction when it crosses the x axis at 0.
the y intercept is -5
The equation is y = -5x -5
You divide 3 on both sides then you equation is the square root of -4x-4 =4 and you square the number on both sides because u need to do the same things on both sides and you get -4x-4=16 subtract by 4 on boyh sides to get -4x=20 and divide by -4 on both aises to get x=-5
I hope this helped i know this explanation is a bit wonky
