Document Summary

You must show your work to receive full credit. Please write neatly: simplify and write with positive exponents: 4x 8: find the equation of the line through the points (6, 4) and (2, 1) , simplify: x2. 9 x2 + 5x + 6 . 2x 3 x2: find the domain of. X + 3 x 7 page 2: solve: 5x + 6 . page 4 (b) use the result of part (a) to nd the other zeros of g(x) : let f (x) = 2x2. 4x 3 . (a) find the vertex of f (x) . (b) find the x and y intercepts of f (x) algebraically: graph h(x) = symptotes. Be sure to nd all horizontal and vertical as- page 5: use the properties of logarithms to write as a single logarithm: 2 ln(x) ln(y + 1) + ln(z: solve by elimination. x + 2y = 1.
