intersect the y axis?

Video Solution

Solution Steps

00:00 Find the intersection point of the function with the Y-axis
00:03 At the intersection point with the Y-axis, X equals 0
00:07 Substitute X=0 in our equation and solve to find the intersection point
00:12 Let's solve and calculate to find the intersection point
00:24 This is the value at the intersection point with the Y-axis
00:28 X = 0 as we substituted at the beginning
00:34 And this is the solution to the problem

Step-by-Step Solution

To solve this problem, we need to determine where the given function intersects the y-axis. This occurs when the x-coordinate is 0. Let's find the y-coordinate when x=0 x = 0 .

The function in question is y=2x2+10 y = 2x^2 + 10 .
Substitute x=0 x = 0 into the function:

y=2(0)2+10=20+10=10 y = 2(0)^2 + 10 = 2 \cdot 0 + 10 = 10 .

Since substituting x=0 x = 0 yields y=10 y = 10 , the point of intersection on the y-axis is (0,10) (0, 10) .

Therefore, the point where the function intersects the y-axis is (0,10) (0, 10) .

Answer

(0,10) (0,10)
