Math Problem Statement

Use the equivalent forms found below to identify the key characteristics of g(x): y-intercept, minimum value, zeros, and end behavior.

Solution

Let's analyze the given function g(x)g(x) using the provided forms.

  1. Forms of the Function: g(x)=2(x4)2+2g(x) = 2(x - 4)^2 + 2 g(x)=2x216x+30g(x) = 2x^2 - 16x + 30 g(x)=2(x3)(x5)g(x) = 2(x - 3)(x - 5)

  2. Key Characteristics:

    • Y-intercept: The y-intercept occurs when x=0x = 0. Using the second form g(x)=2x216x+30g(x) = 2x^2 - 16x + 30, substitute x=0x = 0: g(0)=2(0)216(0)+30=30g(0) = 2(0)^2 - 16(0) + 30 = 30 So, the y-intercept is (0,30)(0, 30).

    • Minimum Value: The first form ( g(x) = 2(x -
