Answer:
which is none of the choices provided.
Are you sure the question is right or even the choices?
You can even write it as:
but this is still not a choice.
Step-by-step explanation:
The vertex form of a quadratic is .
This is called vertex form because it gives you the vertex is .
We are given that which makes our equation:
.
We can find the value of by plugging in the x-intercept (7,0) for
into:
Subtract 25 on both sides:
Divide both sides by 25:
.
So the equation for the quadratic is:
Let's put this into factored form since all the choices are in factored form.
This will require us to multiply the (x-2)(x-2) out:
Factor out -1:
WE need to find two numbers that multiply to be -21 and add to be -4:
Answer and Step-by-step explanation:
one divided by (in parentheses) x minus eight should look like this:
This is a graph of this expression.
