The answer is B. Because it says vertical line so it can’t be y. (Y would be a horizontal line.) Then -4 matches the x value of the expression given and if you plot it on a graph -4 passes though the given point.
Hope this helps.
The domain of the function shown in the graph:
<h3>B. x is all real numbers</h3>
<u>Define x:</u>
Let the cost of the ball be x.
Ball = x
Bat = x + 0.1
<u>The total cost is $1.10:</u>
x + x + 0.1 = 1.1
2x + 0.1 = 1.1
2x = 1
x = 0.5
<u>Find the cost of the bat and the ball:</u>
ball = x = $0.50
bat = x + 0.1 = 0.5 + 0.1 = $0.60
Answer: The ball cost $0.50
