Answer:
All you have to do is insert the first value where the x is, and the second value where the y is.
y = 3x + 5
11 = 3(2) + 5
11 = 6 + 5
11 = 11
So, this is right.
Now, let's check (3,13)
y = 3x + 5
13 = 3(3) + 5
13 = 9 + 5
13 = 14
This is NOT true. So, your answer is: Only (2,11)
Hope this helps!
Answer:
Step-by-step explanation:
Hello, because of the end behaviour it means that the leading coefficient is negative so we can construct such polynomial function as below.
