Explain why the graph of the quadratic function f(x) = x2 + x + 5 crosses the y-axis but does not cross the x-axis. Choose the correct answer below.
O A. The graph does not cross the x-axis because the domain of f(x) is limited to positive values of x. The graph crosses the y-axis
because the range of f(x) is all real numbers.
OB. The graph does not cross the x-axis because there are no real solutions to the equation f(x) = 0. The graph does cross the y-axis at
y = 5 because that is the solution to the equation f(y) = 0.
OC. The graph does not cross x-axis because it cannot be factored. The domain of f(x) is all real numbers, so the graph crosses the
y-axis at x=0.
OD. The graph does not cross the x-axis because there are no real solutions to the equation f(x) = 0. The domain of f(x) is all real
numbers, so the graph crosses the y-axis at x = 0.
