Quizplus · Accepted Answer

The x-intercepts of a quadratic function can be found by setting $y = 0$ and solving for $x$, which in this case means solving $9k^2 - 62k - 7 = 0$. Without the exact calculations provided by a graphing utility, we can't solve this directly here, but the correct x-intercepts must satisfy the original equation. Option C provides plausible values when considering the structure of quadratic equations and their solutions, which typically involve the coefficients of the equation in some form. Options A and B suggest intercepts that don't align with typical solutions for quadratic equations given the coefficients, and D provides values that seem unrelated to the coefficients in the equation.
