Hi Tutor!


23) Points (3, -2) and (-7, 8) are endpoints of the diameter of a circle.

(a) What is the length of the diameter? Give the exact answer, simplified as much as possible. Show work.

(b) What is the center point C of the circle?

(c) Given the point C you found in part (b), state the point symmetric to C about the y-axis



24)  Find the equation for a line which passes through the points (5, -8) and (2, 1). Write the equation in slope-intercept form. Show work.


25) 26. Let f (x) = 3x 2 - 7 and g(x) = x - 5. (a) Find the composite function (f g)(x) and simplify. Show work. (b) Find ( f go )(2) . Show work.
