Find the zeros, if any, of the quadratic function using the quadratic formula. What are the \( x \)-intercepts, if any, of the graph of the function? \( f(x)=2 x^{2}+3+6 x \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) A. The zeros and the \( x \)-intercepts are different. The zeros are \( \square \), the \( x \)-intercepts are B. The zeros and the x-intercepts are the same. They are C. There is no real zero solution and no \( x \)-intercept.

The cost, in thousands of dollars, of airing \( x \) television commercials during a sports event is given by \[ C(x)=150+2,400 x-0.08 x^{2} \] (a) Find the marginal cost function \( C^{\prime}(x) \). \( C^{\prime}(x)=2400-0.16 x \) (b) Use the marginal cost to approximate the cost to air the 5 th commercial. Convert your answer to dollars. The cost to air the 5 th commercial is approximately 2399360 (c) What is the exact cost to air the 5 th commercial? Convert your answer to dollars. The exact cost to air the 5 th commercial is
