Graph the given function using desmos:

f(x)=-3(x-6)²

What are the Root/Zeros of the Function?

Graph the given function using desmos:

h(x)= (x-5)² (x+3)

What are the Root/Zeros of the Function?

Graph the given function using desmos:

h(x)= (x-5)² (x+3)

What is the y-intercept?

Graph the given function using desmos:

h(x)= x(x-2)

What are the Root/Zeros of the Function?

Graph the given function using desmos:

h(x)= x(x-2)

What are the Y-Intercepts of the Function?

Graph the given function using desmos:

h(x)= x(x-2)

Where would the axis of symmetry be?

You are the sales manager for the ferry service that carries passengers from the mainland to the Ohio Islands.  Currently the fare is $10.00 per person and it carries 300 people per day.  The research shows that the company will lose 15 passengers per day for each increase of $1.00 in the fare.  The sales manager uses the function shown to model its daily profit based on the number of $1.00 increases.

f(x)=(300-15x)(x+10)

What is the minimum number of $1.00 increases to avoid a loss? (Break even)
