Answer:
C) 6 inches
Step-by-step explanation:
Given function:
[tex]Y=1.3x-0.8[/tex]
The function compares plant height in inches to the age of plant in weeks.
So, we can say
[tex]Y[/tex] represents height of plant in inches.
[tex]x[/tex] represents age of the plant in weeks.
In order to predict the height of the plant in 5 weeks, we will plugin [tex]x=5[/tex] in the given function and evaluate [tex]Y[/tex]
⇒ [tex]Y=1.3(5)-0.8[/tex]
⇒ [tex]Y=6.5-0.8[/tex]
⇒ [tex]Y=5.7[/tex] inches
Thus the approximate height of plant in 5 weeks would be [tex]\approx 6[/tex] inches
