{(−7, 2), (−2, 2), (0, 1), (4, 5)}

domain={-7,-2,0,4} and range={2,1,5}

Step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
