It easy you just add all the numbers all together
Answer: 9-3-1 or 9-1-y = -5
Answer:
The vertex is at (1, -108).
Step-by-step explanation:
We have the function:
And we want to find its vertex point.
Note that this is in factored form. Hence, our roots/zeros are <em>x</em> = 7 and <em>x</em> = -5.
Since a parabola is symmetric along its vertex, the <em>x-</em>coordinate of the vertex is halfway between the two zeros. Hence:
To find the <em>y-</em>coordinate, substitute this back into the function. Hence:
Therefore, our vertex is at (1, -108).
Answer:
I think it's 4?
Step-by-step explanation:
I used Desmos, a graphing calculator. After plotting the points and drawing a line, I counted 4 points up and 1 point over to get to the next point. 4/1 =4
