<span>The correct answers are:
x = 0
x = 2
Explanation:
When x < 0, the value of y = -</span>
<span>.
When x > 0, the value of y = </span><span>.
When x = 0, there is no value of y mentioned in the conditions; it means that there is discontinuity at x = 0.
When x < 2, the value of y = </span><span>.
When x >= 2, the value of y = 2.
It means that, at x = 2, there is a discontinuity because the graph of y = </span> is not touching the graph of y = 2 at x = 2.
x = 0
x = 2

When x < 0, the value of y = -</span>
When x > 0, the value of y = </span>

When x >= 2, the value of y = 2.
It means that, at x = 2, there is a discontinuity because the graph of y = </span>

If Ian uses 1/20 of the ketchup 4 times, this is equal to 4/20, or 
.
can be simplified to 
, which means we need to work out of 12.2
is equivalent to 20%, which as a decimal is 0.2
0.2 x 12.2 = 2.44 - however, this is how much he has used, and we need to figure out how much is left.
12.2 - 2.44 = 9.76
So, Ian has 9.76 oz remaining :)
