2 answers:
Answer:
{y|y≥0}
Step-by-step explanation:
The parent absolute value function is
This is a V-shaped function whose vertex is at the origin.
This means that, the least y-value is 0 and there is no highest y-value.
The range refers to all y-values for which the function exists.
Therefore the range is
Or
{y|y≥0}

Company A:
Company B:
Step-by-step explanation:
The initial fee is the y-intercept, as that is the cost at x = 0, or the cost before any time has passed. Afterwards, the rate the cost increases is the slope.
Linear equation in slope-intercept form:
where m is the slope and b is the y-intercept.
Company A charges $50 up front and $40 per hour afterwards, so the equation would be:
Company B charges $25 up front and $50 per hour, so:
