Graph the set of real numbers on a number line.{x|-5 ≤ x ≤ -1}

Find all the values of x{“version”:”1.1″,”math”:”x”} where the tangent line is horizontal. fx=x3+9×2+27x-10{“version”:”1.1″,”math”:”fx=x3+9×2+27x-10″}

Suppose that fx=ex{“version”:”1.1″,”math”:”fx=ex”}. What is the average rate of change of fx{“version”:”1.1″,”math”:”fx”} over the interval -1,2{“version”:”1.1″,”math”:”-1,2″}? (Round to 4 decimal places)

Suppose that ft=3t2-2t+5{“version”:”1.1″,”math”:”ft=3t2-2t+5″}. What is the average rate of change of ft{“version”:”1.1″,”math”:”ft”} over the interval t=2{“version”:”1.1″,”math”:”t=2″} to t=6{“version”:”1.1″,”math”:”t=6″}?

Consider the function below: fx=3x-1×2-2x-48{“version”:”1.1″,”math”:”fx=3x-1×2-2x-48″} Check all boxes that have a value of x{“version”:”1.1″,”math”:”x”} where the function is discontinuous. (You may have to check more than one box).

Factor the trinomial, or state that the trinomial is prime. Check your factorization using FOIL multiplication.15×2 + 22x + 8

Solve the quadratic equation by factoring.x2 + 2x – 63 = 0

Use algebra to solve the following limit: limx→49x-7x-49{“version”:”1.1″,”math”:”limx→49x-7x-49″}

What is the domain for the following function? (Give your answer in interval notation) fx=x2-5x+4{“version”:”1.1″,”math”:”fx=x2-5x+4″}
