Yes, the student is correct
Step-by-step explanation:
Given
Required
Does it represent the x intercept
At the x intercept, the value of x is 0.
So, the function becomes
can be compared to
Hence, the student is correct

Let x- intercept represents time
Let y-intercept represents population
Let 1990 represent initial year
Points are (0,14.2)(10,12.4)
slope m=
=
General linear equation
y= mx+b --------------(i)
here m is slope and b is intercept
plug the 1st point in equation
14.2= -0.018(0) + b
b=14.2
y= 0.018x + 14.2
replace y with p(t) and x with t
p(t) = -0.018t + 14.2
