Answer:

  • a. the y-intercept of f(x) is greater than the y-intercept of g(x)

Step-by-step explanation:

Given function:

  • f(x)=(x - 4)^2 - 4

We can work out the function from the table values:

  • g(x) = (x + 2)^2 - 4

Options:

a. the y-intercept of f(x) is greater than the y-intercept of g(x)

  • True. x= 0 ⇒ f(0) = (-4)^2 - 4 = 12, g(0) = 2^2 - 4 = 0

b. The y-intercept of g(x) is greater than the y-intercept of f(x)

  • False. See previous option.  

c. The y-coordinate of the vertex of f(x) s greater than the y-coordinate of the vertex of g(x)

  • False. They are same = -4

d. The x-coordinate of the vertex of g(x) is greater than the x-coordinate of the vertex of f(x)

  • False. -2 vs 4
