Answer:

y- intercept = 3

Explanation:

the y- intercept is the point on the y- axis where the graph crosses it.

the x- coordinate of any point on the y- axis is 0.

substitute x = 0 into the equation to obtain the value of y

y = 2x² - 5x + 3 ( substitute x = 0 )

y = 2(0)² - 5(0) + 3 = 2(0) - 0 + 3 = 0 - 0 + 3 = 3

the y- intercept = 3 or (0, 3 ) in coordinate form
