(-inf,-4) -7 -6 -5 -4 -3 (-4,1) Test each interval -2 -1 8 Because our function must be either positive or negative for each separate interval, we only need to "test" our function for one value in each separate interval. a. Select an x-value in the first interval, (-∞, -4): Evaluate the function f(x) at your selected x-value: Will f(x) be positive or negative on the first interval? Positive 1 b. Select an x-value in the second interval, (-4,1): And evaluate the function f(x) at your selected x-value: Will f(x) be positive or negative on the second interval? Negative c. Select an x-value in the third interval, (1 m): 2 3 (1, inf) 4 5 6 7
