Answer:
zeroes: x = -9 and x = -7
Step-by-step explanation:
f(x)=(x+8)^2−1
A "zero" refers to when the y-value on the graph is zero.
0 = (x+8)^2 - 1
1 = (x+8)^2
+ or - 1 = x+8
so break them apart into two equations
x+8 = 1 OR x+8 = -1
x = -7 OR x = -9
You can plug both back in to check that the equation works!
Answer:
plug it in. y2-y1 over x2-x1
Step-by-step explanation:
Answer:
Step-by-step explanation:
we have
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
remember that
The answer should be (4,0) before it on the x axis
Answer:
This question is incomplete, so I can not give you an exact answer, but I can give you the answer for the general case.
If we have a function f(x), the average rate of change between the values:
x = a and x = b,
is given by:
So if we want to find the rate of change from:
x = -1 to x = 1
it is just:
So just to show an example, if:
f(x) = 3*x^2 - 5
the average rate of change in that interval will be:
