PreCalculus 1.3 - 1.5

State the domain of the function (only one answer is the best)

• all real numbers
• x cannot equal 6
• x cannot equal 6 or 0
• x equals 6 and 0

Choose the appropriate answer

• 86; 81
• 40; 45
• 40; 86
• 81; 45

State the domain

• (-infinity, infinity)
• [-infinity, infinity]
• [-16, infinity)
• [-4,8]

State the range

• (-infinity, infinity)
• [-infinity, infinity]
• [-16, infinity)
• [2, infinity)

Determine whether the function is even, odd, or neither

• even
• odd
• neither
• even and odd

If f(x) = -4x - 5 and 
g(x) = 3 - x, 
what is g(-4) + f(1)?

• 7
• -2
• -9
• -10

f(x) = 3x² + 7x and g(x) = 2x² - x - 1, find (f - g)(x).

• x² + 8x + 1
• x² + 6x - 1
• 5x² + 8x - 1
• x² + 8x -1

f(x+2) - 4

• horizontal shift to the right 2 and vertical shift up 4
• horizontal shift to the right 2 and vertical shift down 4
• horizontal shift to the left 2 and vertical shift up 4
• horizontal shift to the left 2 and vertical shift down 4

Where is f(x)>0?

• (-6,-4) ∪ (4,6)
• (-5, 2) ∪ (5,6)
• x = -4, 6
• (-6,0) ∪ (4,6)

Where is f(x) decreasing?

• (-6,-4) ∪ (4,6)
• (-4,-2) ∪ (1,4)
• (-4,-2) ∪ (1,2)
• (-5,2) ∪ (5,6)
