See explanation below
Step-by-step explanation:
Domain is referred as the x values of the function
The x values of the graph: from 0 t0 9
Domain = 0 ≤ x ≤9
Range is referred to as the y values of the function
The y values of the graph: from 150 to 240
Range = 150 ≤ y≤ 240
150 is gotten when x = 9, y = 150
when x= 0, y = 240
The equation of the line is the form of: y = mx + c
c = y-intercept
This the point the line touches the y axis.
From the graph, the line touches the y axis at $240
c = y-intercept = 240
m = slope = change in balance/ change in number of visits
we will pick any two points (x, y): (0, 240) and (8, 160)
m = (160-240)/(8-0) = -80/8
m = slope = -10
It is a negative slope as it is going downwards
Putting the value of c and m in the equation form:
y = -10x + 240
The x intercept is gotten when you equate y in the equation of the line to zero.
0 = -10x + 240
10x = 240
x = 240/10
x = 24
The x intercept is 24
Zeros of the equation are the values of x that cause the equation to be equal to zero. We wiil make y = 0. This is also the x intercept.
Reason: when y = 0
the value of x obtained is the x-intercept
zeros = 24
