18. Brad is designing an A-frame house and needs to include angular dimensions in the diagram below. Angles 1, 2 and 3 add up to 180 °. The sum of angles 3 and 4 is 180 °. Angle 1 is 50 ° and angle 2 is 20 °. Write an equation that you can use to determine the measure of an angle 4.

Show all work to identify the discontinuity and zero of the function f of x equals 6 x over quantity x squared minus 36

Drag the tiles to the correct boxes to complete the pairs. match the exponential functions with their horizontal asymptotes and y-intercepts. f(x) = 7x − 4 f(x) = 3x+2 + 4 f(x) = 9x+1 − 4 f(x) = 2x + 4 horizontal asymptote and y-intercept exponential function horizontal asymptote: y = 4 y-intercept: (0, 5) arrowboth horizontal asymptote: y = -4 y-intercept: (0, 5) arrowboth horizontal asymptote: y = -4 y-intercept: (0, -3) arrowboth horizontal asymptote: y = 4 y-intercept: (0, 13) arrowboth
