Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ra y says the third-degree polynomial has 4 intercepts. Kelsey argues the function can have as many as 3 zeros only. Is there a way for the both of them to be correct? Explain your answer.

Hints: Intercepts could mean either x-intercept or y-intercept. 3 zeroes means three x-intercepts.
Sure there is. The function has three zeros ... it crosses the x-axis in 3 places. Those are three x-intercepts. It also crosses the y-axis. That's not a 'zero' or solution, but it's the fourth intercept. I slapped together a "third-degree polynomial function" in a hurry that I think does the job. I'm not positive ... you should check it: f(x) = x³ + 6x² + 11x + 6 ==> f(x) is zero when x = -3 or -2 or -1 ... those are three x-intercepts. ==> f(x) is 6 when x = 0 ... that's the y-intercept. I don't know what "the first pattern in the coaster plan" means.

Step-by-step explanation:
You would distibute first distribute
6x-10=8
add 10 on both sides
6x=18
Then you divide 6 on both sides to get x by itself so
x=3
Answer:
pizzeria1
Step-by-step explanation:
Given data
pizzeria1
Diameter=16in
Radius= 16/2= 8in
Area= πr^2
Area= 3.132*8^2
Area= 201.09 in^2
pizzeria2
Diameter=15in
Radius= 15/2= 7.5in
Area= πr^2
Area= 3.132*7.5^2
Area= 176.74n^2
