Consider the function with. Plug x0 into the equation and solve the resulting equation 5 y15 for y use the equation solver. The eqy eq-intercept is the point eq 0f 0 eq.

Replace every x in the polynomial with 0. How many y intercepts does fx have. The graph of y f x passes through the point 4 1.

The y intercept is 0 14. This video introduces how to determine the maximum number of x-intercepts and turns of a polynomial function from the degree of the polynomial function. Determine whether the graph of f opens upward or downward and whether the graph is wider narrower or the same as the graph of find the axis of symmetry and the vertex.
