CHAPTER O Review Exercise 1. Let f(x) = x³ + ¹. Evaluate f(1), ƒ(3), f(-1), f(-). and f(√2). 2. Let f(x) = 2x + 3x². Evaluate f(0), f(-1), and f(1/2). 3. Let f(x)=x²-2. Evaluate f(a - 2). 4. Let f(x) = [1/(x+1)] - x². Evaluate f(a + 1). Determine the domains of the following functions. 1 x(x + 3) 7. f(x)=√x²+1 √3x 9. Is the point (-3) on the graph of the function h(x) (x²-1)/(x² + 1)? 5. f(x) = 6. f(x)=√x-1 8. f(x) = 10. Is the point (1, -2) on the graph of the function k(x) x² + (2/x)?
