    1. Use the quadratic formula to determine the x-intercepts (if any) of the following function. Then evaluate the function for several values of x, and use the resulting points to graph the function. Show your work.

    F(x) = 7x^2 - 28x + 28

    2. Use the discriminate to determine whether the following equations have solutions that are: two different rational solutions; two different irrational solutions; exactly one rational solution; or two different imaginary solutions. Show your work.

    9 - 2a^2 = 6a + 2

    3. Complete the square. Then write the trinomial square in factored form. Show your work

    x^2+2/3 x

    4. Write a quadratic equation having the given numbers as solutions.

    3, -8
