[tex]y=4x^{2} +1[/tex] has a y-intercept of 1 and [tex]y=4x^{2}[/tex] a y-intercept of 0.
The y-intercept is the point where a graph crosses the y-axis. In other words, it is the value of y when x=0.
The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
