1.     Given f(x) = 9x³ − 5x² + 7x − 8 and g(x) = 11x² − 3x − 4 find (f + g)(x).

• (f + g(x) =

  20x⁵ − 8x³ + 3x − 8

• (f + g(x) 

  =20x³ −8x² + 7x − 12

• (f + g(x)= 

  9x³ − 6x² + 4x − 12

• (f + g(x)=

  9x³ + 6x² + 4x – 12

  Given f(x) = x² + 4x − 12 and g(x) = 2x, what is the domain and range of [f ∘ g](x)?

• The domain and the range are all real numbers.

• The domain is all real numbers and the range is y ≥ −16.

• The domain is x ≥ −16 and the range is all real numbers.

• The domain is {x | −2 < x < 1} and the range is y ≥ −16

Which is the inverse of f(x) = x² + 6x + 8?

•  3(x + 5)⁸

• ±3(x + 5)⁸ 

• 3(x + 5)³

• ±3(x + 5)³
