If I have an equation in which x = pounds, and y = total cost, can I substitute quarts into the equation

Yes, you can

Step-by-step explanation:

As a point of reference, assume the equation is:

Where

and

In standard unit of conversion:

So:

Substitute 0.4793x for x in

The above equation is the equivalent of in quarts

So, irrespective of what the equation is, you can always substitute quarts into the equation.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

answer: 590
