5x +8 3x-5 Find the following for the function f(x) = (a) f(0) (e) fx) (f) f(x +3) (g) f(7x) (h) fix +h) (c) f(-1)- Simplify your answer. Type an integer or a simplified fraction.) Simplify your answer. Use integers or fractions for any numbers in the expression.) (e)-f(x)= Simplify your answer. Use integers or fractions for any numbers in the expression.) (f) f(x + 3)= (Simplify your answer. Use integers or fractions for any numbers in the expression.) (g) f(7x) = (Simplify your answer. Use integers or fractions for any numbers in the expression) (h) f(x + h) = [] (Simplify your answer. Use integers or fractions for any numbers in the expression.) Enter your answer in each of the answer boxes.Explanation / Answer
f(0) = -8/5
----------------------------------------------------------
f(1) = (5 + 8)/(3 - 5)
= 13/-2
= -13/2
----------------------------------------------------------
f(-1) :
(-5 + 8)/(-3-5)
= -3/8
-----------------------------------------------------------
f(-x) = (-5x + 8)/(-3x - 5)
Take negative all over :
f(-x) = (5x - 8)/(3x + 5)
------------------------------------------------------------
-f(x) :
-(5x + 8)/(3x - 5)
As in
(5x + 8)/(5 - 3x)
------------------------------------------------------------
f(x+3):
(5(x+3) + 8)/(3(x+3) - 5)
(5x + 15 + 8)/(3x + 9 - 5)
(5x + 23)/(3x + 4) ---> ANS
-------------------------------------------------------------
f(7x):
[5(7x) + 8)]/(3(3x) - 5)
(35x + 8)/(9x - 5)
--------------------------------------------------------------
f(x+h) :
[5(x+h) + 8]/[3(x+h) - 5]
(5x + 5h + 8)?(3x + 3h - 5) ---> ANS
