So for this, we will have to find the zeros (x-intercepts) of the equation. In this case, we will be using the quadratic formula, which is (a = x^2 coefficient, b = x coefficient, c = constant). Using our info, our equation is such:
Firstly, solve the multiplications and the exponents:
Next, do the addition:
Next, plug in the equations into the calculator and your answer will be:
Since we can't have negative time in this situation, it can't be -0.41 seconds. Which means that the object is visible for about 0.60 seconds, or C.
