Domain- (-5 ≤ x ≤ 10)
Range- (-3 ≤ y ≤ 5)
x-intercepts- (3, 8)
y-intercept- (2)
f(1)- 3
a. Domain:
The x-axis extends from -5 to 10, so the domain is {-5 ≤ x ≤ 10}.
b. Range:
The y-axis extends from -3 to 5, so the range is {-3 ≤ y ≤ 5}.
c. x-intercepts:
An x-intercept occurs when the line crosses the x-axis, which means y is 0. Looking at the graph, the line crosses the x-axis at x=3 and x=8. Therefore, the x-intercepts are {3, 8}.
d. y-intercepts:
A y-intercept occurs when the line crosses the y-axis, which means x is 0. Looking at the graph, the line crosses the y-axis at y=2. Therefore, the y-intercept is {2}.
e. f(1):
To find the function value f(1), we need to find the point on the graph where x is 1. Looking at the graph, the point where x is 1 is (1, 3). Therefore, f(1) = 3.
