Answer:
1. f(β9) = -66 , g( 1 ) = 27 Β (Please double-check your given options, there must have been a typographical error for Option C for g( 1 ) = 29). g( 1 ) is supposed to be 27.
2. Option A: f(β9) = 25, g(β1) = 21
Step-by-step explanation:
1.Find the value of f(β9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20xβ2
f(x) = 8x + 6
f(β9) = 8(-9) + 6 = -66
g(x) = 9x + 20x β 2
g( 1 ) = 9( 1 ) + 20( 1 ) β 2 = 27
None of the given choices were correct (unless there's a typo error for Option C β it's supposed to be g( 1 ) = 27 instead of 29?) because the correct answers are: f(β9) = -66 and g( 1 ) = 27
2. Β f(β9) and g(β1) if f(x) = β3x β 2 and g(x) = 3xΒ³ β 24x
f(x) = β3x β 2
f(β9) = β3(β9) β 2 = 25
g(x) = 3xΒ³ β 24x
g(β1) = 3(β1)Β³ β 24(β1) = 21
Therefore, the correct answer is Option A: f(β9) = 25, g(β1) = 21
