Math 2B Review 1 Match the BEST description to its definition. Use a graph as needed. 1. All possible y-values (Range) 2. Points where the graph crosses or touches the x-axis. (Roots) Name Marwa 3-21 Domain Maximum Slope 3. The highest range value on the graph of a function in a given interval. (Maximum)Y-intercept 4. Said of a function that has a positive rate of change over a given interval 5. The average slope of a graph over a given interval(ARC) End Behavior Roots 6. The lowest range value on the graph of a function in a given interval (Minumum) Increasing 7. All possible x-values (Domain) Average Rate of Change 8. What happens to the range as the domain goes to either of End Behavior) Minimum 0. 9. The rate of change over a given interval; the vertical change / horizontal change. Range 10. Find the average rate of change for a function for [3,2] If we have (-3, 21) and (2, 7). 11. Find the average rate of change for a function for [2, 8] If we have (2, 18) and (8, 4). 12. Find the roots and y-intercept of the function. f(x) = (x + 3)(x - 4) Roots: f(x)=(x+3)(x-4) y-int f(0) = (0+3) (0-4) ab=0 1= 3 +3 =0 30-4 y-int = -12 124-4=0 13. Find the roots and y-intercept of the function. f(x) = 3(x-5)(2x + 3) Roots: f(x)=3(x-5)(2x+3)= 0 3 3 x-5)(2x+3)=0 b = 0 4
