B

Step-by-step explanation:

For example let's set up a quadratic equation.

Let's use

f(x) = (x + 10)^2 + 7

The seven is the y intercept so let's ignore that and focus on the ten.

When we graph this we end up getting the picture below. Now, why is the vertex at -10? The reason is the equation starts off with a negative sign.

f(n) = (h - x) + k

So, if x is positive then it will remain negative but still go in positive just because the equation has a subtraction sign in it.

As a result when the equation has + 10, it shows that the x is negative because x = -10 and when you do

h- (-10) it becomes h + 10.

mental cunning

explanation:

he is often referred to as a man of twists and turns

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
