Problem 1
Sketch the graph of the function defined by the sum of function
Graph of 2 functions on grid. Horizontal x axis from negative 10 to 8, by 2’s. Vertical y axis from negative 10 to 8, by 2’s. Function y equals f of x, non linear function, runs near x axis in quadrant 2, passes through 0 comma 1, 1 comma 2, 2 comma 4, and 3 comma 8. Function y equals a of x, horizontal line, passes through negative 10 comma 3, 0 comma 3, and 8 comma 3.
