Using a linear function, it will take 8 years for the Springfield zoo to have 35 gorillas.
What is a linear function?
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For this problem, the parameters are given as follows:
m = 4, b = 3.
Hence the number of gorillas after x years is given by:
G(x) = 3 + 4x.
It will have 35 gorillas when:
G(x) = 35.
Hence:
3 + 4x = 35.
4x = 32.
x = 32/4
x = 8.
