Unit 5, Activity 8, General Assessment, Spiral with Answers Blackline Masters, Advanced Math-Pre-Calculus Page Comprehensive Curriculum, Revised 2008 1781. Simplify: 25332xxx+−+2x - 1 2. Find the inverse of f(x) = x2– 1. Is the inverse a function? Why or why not? The inverse is yx=±+1. It is not a function because y is matched to two values. 3. Given: kx+ 2y= 6 8x+ ky= 8 Find the value of kthat makes the lines parallel. k = 4 4. x2–kx– 15 = 0 One root of this quadratic is 5. Find the value of k. k = 2 5. If one leg of a right triangle is 4 and the other is 6, find the hypotenuse. 2136. In the triangle below find BCin simplest form. BC=10 37. Given the parent function f(x) = x2.
