Problem 1
Here are graphs of functions
and . For each, determine the value of so that . Graph of 2 functions on grid. Horizontal x axis from negative 10 to 30, by 5’s. Vertical y axis from negative 40 to 80, by 20’s. Y equals f of x, dotted, begins in quadrant 2, decreasing, passing through 0 comma 0 until about 5 comma negative 25, then increasing, passing through 10 comma 0. Y equals g of x, solid, begins in quadrant 2, decreasing, passing through 0 comma 0 until about 15 comma negative 25, then increasing, passing through 30 comma 0.Graph of 2 functions on grid. Horizontal x axis from negative 6 to 6 by 2’s. Vertical y axis from negative 100 to 20, by 20’s. Both functions increasing, then decreasing, then increasing. Y equals f of x, solid, passes through 0 comma negative 50 and 3 point 125 comma 0. Y equals g of x, dotted, passes through 0 comma negative 50 and 5 comma 0.Graph of 2 functions on grid. Horizontal x and vertical y axis both from negative 1 point 5 to 1 by 0 point 5’s. Y equals f of x, dotted line, passes through 0 comma 0 and point 693 comma 1. Y equals g of x, solid line, passes through 0 comma 0 and 0 point 277 comma 1.Graph of 2 functions on grid. Horizontal x axis from negative 10 to 4 by 2’s. Vertical y axis from 0 to 2 by 1’s. Y equals f of x, dotted line, passes through 0 comma 0, 1 comma 1, 4 comma 2. Y equals g of x, solid line, passes through 0 comma 0, negative 2 comma 1, negative 8 comma 2.
