Answer:

Domin of f(x): -4 to 1

Domain of g(x): -1 to 2

Range of f(x): 4 to -6

Range of g(x): -1 to 5

Initial starting value of f(x) is 4

Initial starting value of g(x) is -1

Y-intercept of f(x) is -4

Y-intercept of g(x) is 3

Slope of f(x): -2

Slope of g(x): -2

Step-by-step explanation:

The domain of a function is the set of all possible input values (x values) for which a function is defined.

Looking at the table, we can see that the domain of f(x) is from -4 to 1

Looking at the graph, we can see that the domain of f(x) is from -1 to 2

The range of a function is the set of all possible output values (y values) for which a function is defined.

Looking at the table, we can see that the range of f(x) is from 4 to -6

Looking at the graph, we can see that the range of f(x) is from -1 to 5

We can see from the table that the initial starting value of f(x) is 4

From the graph, we can see that the initial starting value of g(x) is -1

The y-intercept is the point where the graph crosses the y-axis. At y-intercept, x = 0

We can see from the table that when x = 0, f(x) = -4, therefore the y-intercept of f(x) is -4

We can see from the graph of g(x) crosses the y-axis at y = 3, therefore the y-intercept of g(x) is 3

The slope(m) of a graph can be determined using the below formula;


m=(y_2-y_1)/(x_2-x_1)

We can determine the slope of f(x) using the points (-2, 0) and (0, -4) where x1 = -2, y1 = 0, x2 = 0, and y2 = -4;


m=(y_2-y_1)/(x_2-x_1)=(-4-0)/(0-(-2))=(-4)/(2)=-2

We can determine the slope of g(x) using the points (-1, 5) and (2, -1) where x1 = -1, y1 = 5 and x2 = 2, and y2 = -1;


m=(y_2-y_1)/(x_2-x_1)=(-1-5)/(2-(-1))=(-6)/(3)=-2
