A3 - 1ST SEMESTER FINAL

Which point below is NOT part of the solution set?

• (0, 0)
• (5, 1)
• (-3, -1)
• (20, -5)

Solve:
∣ 2x + 9 ∣ = 15

• x = 3 
• x = 3
  x = -6
• x = 3
  x = -12
• x = 6
  x = -12

For the function f(x) = -3(x-1)
 find f(0)

• 0
• -3
• 3
• -1

Write the inequality in interval notation.

• (-2,5)
• (-∞,-2)⋃(5,∞)
• [-2,5]
• (-∞,-2]∪[5,∞)

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)

  The blue function is f(x)=|x|, red function's equation must be

• |x+2|
• |x|+2
• |x-2|
• |x|-2

Name the parent function.

• cube root
• quadratic
• cubic
• square root

Compare the following function to its parent graph:  f(x) = (x-7)^2

• It has been shifted to the right 7 units
• It has been shifted to the left 7 units
• It has been shifted down 7 units
• It has been shifted up 7 units

What is the domain of the function in the graph?

• (-∞,∞)
• [0,∞)
• (-∞,0]
• [-∞,∞]

If the blue is f(x)=x^2, then the red must be

• x²-5
• x²+5
• (x-5)²
• (x+5)²
