Y=9(x^2+3x-x-3)
y=9(x^2+2x-3)
y=9x^2+18x-27
Answer: 104.5 seconds
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
Six students eat 6 apples in 33 seconds.
The proportion is: number of apples eaten /time
6 apples /33 seconds = 6/33
For 19 apples:
19 apples / x seconds =19/x
6/33 = 19/x
Solving for x:
x = 19 / ( 6/33)
x = 104.5 seconds

Answer: A - (1,4)
Exponential functions always have a horizontal asymptote, and the equation of it is y=0, and the equation has a 4, so it is exponentially moving up by 4. Also, this type of function never intersects 0,0
