Find Y-Axis Intersection: Solving y=(x-3)²-4 Quadratic Function

Question

Find the intersection of the function

y=(x3)24 y=(x-3)^2-4

With the Y

Video Solution

Step-by-Step Solution

The problem asks us to find where the parabola given by y=(x3)24 y = (x-3)^2 - 4 intersects the y-axis. The intersection with the y-axis occurs where x=0 x = 0 . Let's find the value of y y by substituting x=0 x = 0 into the equation:

y=(03)24 y = (0 - 3)^2 - 4

Simplify inside the parentheses:

y=(3)24 y = (-3)^2 - 4

Calculate (3)2(-3)^2:

y=94 y = 9 - 4

Subtract 4 from 9:

y=5 y = 5

Thus, the intersection of the function with the y-axis occurs at the point (0,5) (0, 5) .

The correct answer from the choices provided is (0,5)(0,5).

Answer

(0,5) (0,5)
