Video Solution

Solution Steps

00:00 Match the function to the appropriate graph
00:03 We notice the coefficient of X squared is positive, so the function is smiling upward
00:08 We want to find the intersection point with the Y-axis
00:11 We'll substitute X=0 and solve to find the intersection point with the Y-axis
00:15 This is the intersection point with the Y-axis, which is also with the X-axis
00:22 We'll draw the graph according to the function type and the intersection point we found
00:25 And this is the solution to the question

Step-by-Step Solution

The function given is y=6x2 y = 6x^2 . This is a quadratic function, a type of parabola with vertex at the origin (0,0), because there are no additional terms indicating a horizontal or vertical shift.

First, note the coefficient of x2 x^2 is 6 6 . A positive coefficient indicates that the parabola opens upwards. The value of 6 6 means the parabola is relatively narrow, as it is stretched vertically compared to the standard y=x2 y = x^2 .

To identify the corresponding graph:

  • Recognize that a function of the form y=ax2 y = ax^2 with a>1 a > 1 indicates a narrower parabola.
  • Out of the given graphs, we should look for an upward-opening narrow parabola.

Upon examining each graph, you find that option 2 shows a parabola that is narrower than the standard parabola y=x2 y = x^2 and opens upwards distinctly, matching our function y=6x2 y = 6x^2 .

Therefore, the correct graph for the function y=6x2 y = 6x^2 is option 2.
