A graph of the function _____ has no x intercepts.

y = x^2
y = 3
y = 1/x
y = x

The correct answer is: y = 3

A graph of y = 3 is a horizontal line with a y-intercept of 3. Since there is no x term in the equation, there is no way for the graph to cross the x-axis and therefore, it has no x-intercepts. Option A, y = x^2, is a parabola with two x-intercepts. Option C, y = 1/x, is a hyperbola with two x-intercepts (excluding the point at which the asymptotes intersect). Option D, y = x, is a line with a slope of 1 and a y-intercept of 0, so it intersects the x-axis at the point (0,0).
