Question

If the equation below is graphed in the xy-plane, what is the value of its y-intercept?

y = 2x² - 5x + 3

Answer 1

The y-intercept is the point at which the graph of the equation crosses the y-axis. This occurs when x = 0, so we can substitute x = 0 into the equation to find the y-intercept:

y = 2(0)² - 5(0) + 3

y = 3

So the y-intercept of the equation is 3.
