Answer:
Mistake: -3-5=-2, -3-5=-8
Step-by-step explanation:
-3-(7x+5)+9x=-8+3x+10
-3-7x-5+9x=4x+2
-8+2x=4x+2
-8-2=4x-2x
-10=2x
-10/2=x
-5=x
Answer: i) f(-9)= 66
ii) .
iii)
Step-by-step explanation:
The given function : .
i) For f(-9) , the independent variable is x= -9.
Put x= -9 in given function , we get
Thus , f(-9)= 66
ii) For f(x+1) , the independent variable is x= x+1.
Replace x by x+1 in given function , we get
.
Thus , .
iii)For f(-x) , the independent variable is x=-x.
Replace x by -x in given function , we get
.
[∵ (+)(-)=(-)]
Thus ,
