1) write the equation of the function with parent function, f(x)=x^2 that is shifted 2 units right , reflected about the x-axis, and shifted 3 units up .
2) write the equation of the function with parent function, f(x)=1/x, that is reflected about the x-axis, has a vertical stretch of 3, and shifted 2 units up.

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
