Liam will spin the pointer one time what is the probability the pointer will land on red

3/8

Step-by-step explanation:

The given function is . This is a quadratic function because the degree of the polynomial, the variable with the highest exponent, is 2.

All quadratic functions can be expressed in the form .
In your equation,
a = -1
b = 50
c = -264

The equation for the x-coordinate vertex of a quadratic function is .
Applying this to the given function,
.

Now plug the value of x into f(x) to find f(x) (aka the y-coordinate).


The vertex is (25, 361)

Part B
The x-intercept is where the graph crosses the x-axis. Therefore, f(x) (aka the y-coordinate) will be 0. So the x-intercept will be in the form of (x, 0).

To find the x-intercept, set f(x) = 0.
.

Therefore the x-intercepts will be at (6, 0) and (44, 0)
