14. 2z^2 - 4z + 2 =0

First factor out a 2

2(z^2 - 2z + 1) = 0

Now factor the z^2

2(z - 1)(z - 1)

z = 1 , 1 A

15. x^2 +6x = 0

factor out an x

x(x + 6) = 0

X = 0, -6 B

16.

6x^2 - 17x -14 = 0

Factor

(2x - 7)(3x +2) = 0(use the diamond method so solve this)

x = 7/2 , -2/3 D

17.

Simplify

15x^2 - 14x - 8 = 0 (use the diamond method to factor)

(3x -4)(5x + 2) = 0

x = 4/3, -2/5 B

F(x) = x^2. What is g(x)
Alexeev081 [22]

Answer:

g(x) = - x² - 4 ⇒ A

Step-by-step explanation:

Let us revise the reflection and translation of a function

  • If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x)
  • If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)
  • If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)  
  • If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)  
  • If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k  
  • If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) – k  

f(x) = x² is the blue curve

g(x) is its image is the red curve

∵ g(x) is the image of f(x)

∵ f(x) is opened upward

∵ g(x) is opened downward

→ That means the sign of y-coordinates of all points on the blue

   graph are opposite

∴ f(x) is reflected about the x-axis

∴ Its image is - f(x)

∵ The vertex of f(x) is (0, 0)

∵ The vertex of g(x) = (0, -4)

→ That means the function translated 4 units down

∴ - f(x) is translated 4 units down

∴ Its image is - f(x) - 4

∴ g(x) = - f(x) - 4

∵ f(x) = x²

∴ g(x) = - x² - 4
