With the X

Video Solution

Solution Steps

00:00 Find the intersection point of the function with the X-axis
00:03 At the intersection point with the X-axis Y =0
00:07 Therefore, we substitute Y =0 and solve to find the intersection point with the X-axis
00:13 Extract the root to eliminate the exponent
00:27 Isolate X
00:36 This is the X value at the intersection point, we substitute Y=0 as we did at the point
00:44 And this is the solution to the question

Step-by-Step Solution

To find the intersection of the function y=(x+114)2 y = (x + 1\frac{1}{4})^2 with the x-axis, we set y=0 y = 0 since intersections on the x-axis have a y y -coordinate of zero.

Therefore, our equation becomes:

(x+114)2=0 (x + 1\frac{1}{4})^2 = 0 .

To solve this equation, take the square root of both sides:

x+114=0 x + 1\frac{1}{4} = 0 .

Next, solve for x x by subtracting 114 1\frac{1}{4} from both sides:

x=114 x = -1\frac{1}{4} .

Thus, the intersection point of the function with the x-axis is (114,0)(-1\frac{1}{4}, 0).

After checking the provided answer choices, the correct choice is:

: (114,0) (-1\frac{1}{4},0)

Therefore, the solution to the problem is (114,0)(-1\frac{1}{4}, 0).

Answer

(114,0) (-1\frac{1}{4},0)
