The function graphed in piecewise form is

(2 if 0 < x <= 4)

f(x) = (-x/5 - 5 if -5 < x <= 0)

What is piecewise function?

A piecewise function is a mathematical function defined by different rules or formulas for different intervals or subdomains.

The first line is a graph of y = 2 for values of x from 0(not inclusive) to 4(inclusive)

i.e fx = 2 if (0< x <= 4)

For the second line

Slope = Rise/Run

let take points (-5,-4) and (0,-5)

m = -5-(-4)/(0-(-5)

= -5+4/0+5

= -1/5

Using the equation of line

y = mx + b

where b is the y-intercept

y = -x/5 - 5

Therefore, the function graphed in piecewise form is

(2 if 0 < x <= 4)

f(x) = (-x/5 - 5 if -5 < x <= 0)
