Give the value of fx in each of the fx x fx In x x 10 fx
Solution
1) f(x) = x^n
= 4^-2
= 0.06
2) f(x) = log x ; x= 10
= log 10
= 1
3) f(x) = loga(x) ;x=238,a=2
= log2(238)
= 7.89
4) f(x) = 1/x ; x=-3
= -0.33
5) f(x) = e^x x=-1.5
= e^-1.5
= 0.22
6) f(x) = |x| x=-10
= |-10|
= 10
7) f(x) = a^x x=4,a=-2
= -16
8) f(x) = sin x x=0.75
= sin 0.75
= 0.68
9)f(x) = arcsin x
x = 0.5
f(0.5) = arcsin 0.5
f(0.5) = 0.52 rad
10) f(x) = cos(x)
=cos(45)
f(x) = 0.52
