if you horizontally stretch the quadratic parent funtion, f(x)=x^2, by a factor of 5, what is the equation of the new function?

- "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."

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
