The frequency polygon shows the amount of time of group of students to took solve a puzzle How many students took between 5 to 10 minutes

the one below it is a function

if im not mistaking its

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
