All the input values shown on the x-axis
You can either make a table using any numbers you would like (I would suggest -5 to 5) and then graphing the rule
ex. (7/2)(-5)-2 = -19.5 (I multiplied (7/2) by -5 and then subtracted 2)
Or you can put the rule in a graphing calculator and check the points from there
The answer is 15
these chords are congruent because the radius of the circle are perpendicular to the them
so we can find EF by making an equation:

so EF is = 3(15)+5=50
good luck
