Use the parabola tool to graph the quadratic function f(x)=2x2+24x+70. Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

Well, PEMDAS can come in handy for this.

So, if we're solving for the value of "f" then follow these steps to find what it equal!

-4(f)+25-(5(f)+5=?

? = 0

Change your "symbols" from addition to subtraction and MAYBE the other one to multiplication

25 - 4(f) - 5(f) + 5 = ?

Remember I said the mystery number (?) is 0

Lets try to multipy your numbers by a negative 1 (-1) in this part of the problem ➡-9(f) = 0

We can divide from "9" as well

From the looks of it you have one solution to this problem

So, therefore your would have to be➡ f = 0
