Hi there! The domain of a function refers to the values that can be validly input for x. In laymen's terms, domain is the x-values that exist on a graph of the equation.
If we were to plug in y=-2x+5 into a calculator that shows an infinite graph, we would see that the line of the equation would extend both ways infinitely! This means that all real numbers can be inputs for x, because for every x value that exists there is a corresponding y value.
This means that D. All real numbers, is your answer.
Hope it helps! :)
<span>An equation for the number of donuts y that are left at the end of the day when x donuts are being used during the day is y=24-x. You would subtract x, the number of donuts being used from 24, the total amount of donuts. To get your y.</span>

Step-by-step explanation:
Explanation in the Images. I can clarify further if needed.
If a quadratic equation has solutions 
and 
, then we can write it as
So, in your case, we have (let me write 1.5 as 3/2 and -0.25 as -1/4)
If we don't want decimal coefficient, we can multiply the whole expression by 8:
Answer: a > 4
<u>Step-by-step explanation:</u>
-5 + a > -1
<u>+5 </u> <u>+5 </u>
a > 4
Graph: 4 o-----------→
