Albert receives $0.30 per pound for 1 to 49 pounds of glass bottles he recycles. he receives $0.40
per pound if he recycles more than 50 pounds. is the amount of money albert receives a function
of the weight of the bottles he recycles? explain your reasoning.

Yes

Step-by-step explanation:

The amount of money Albert receives is described by the expression

The graph is shown below.

To determine if the relation is a function,  we can use the vertical line test:  

If a vertical line crosses the graph more than once in any location, the relation is not a function.

We see that at no place will a vertical line intersect the graph more than once.

The relation is a function.

i dont know sorry

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
