Simplify the expression
Answer:
(4,-7) is the vertex
Step-by-step explanation:
The equation of the parabola is of the form
y= a(x-h)^2 +k
where (h,k) is the vertex
f(x) = -2(x – 4)^2 – 7
(4,-7) is the vertex
Answer:
y = 6
Step-by-step explanation:
Lets first try to find the slope between the two points. Note, if the slope is 0, then the line would be a horizontal line. If the slope is undefined, then it is a vertical line.
We can use the slope formula to find the slope between the two lines, but notice something. The slope formula is technically just the change in y divided by the change in x. Between the two points, the y-value does not change and the x-value does change. This means that the change in y is 0, but the change in x is not zero. This means that the slope would be 0, resulting in a horizontal line.
Now, we know that the resulting line is horizontal, meaning it will take the form of y = _. Since the y-values for both of the points is 6, it makes sense to say that the equation for the line would be y = 6.
I hope this helps. Happy studying.
