Answer:
Gabby plants grow faster
Step-by-step explanation:
You just have to plug x from 0 to 3 in tina's equation
In which x equals number of weeks.
If we put x = 3
f(3) = 3 + 1.5 which is equal to f(x) 4.5.
f(x) is height in inches here.
This means at the end of 3 weeks tina plants grows 4.5 Inches while gabby's plant grows by 7 inches as you can see in the table at the endof 3 weeks.
So Gabbys plant grow faster
