Step-by-step video solution

Watch the teacher solve the problem with clear explanations
00:00 Match the function to the appropriate graph
00:03 Notice the coefficient of X squared is positive, so the function is 'happy'
00:08 We want to find the intersection point with the Y-axis
00:12 Substitute X=0 and solve to find the intersection point with Y-axis
00:19 This is the intersection point with the Y-axis
00:22 According to the function type and intersection point
00:26 We can conclude there are no intersection points with the X-axis
00:31 Let's draw the graph according to the function type and intersection points we found
00:34 And this is the solution to the question
