Give the value of fx in each of the fx x fx In x x 10 fx

Give the value of f(x) in each of the f(x) = x f(x) - In x x = 10 f(x) -log_a (x) f(x) - 1/x x = -3 f(x) - e^x f(x) - |x| x = -10 f(x) = a x = 4, a = -2 f (x) - sin x x = 75 radians f(x) = arcsin x x = 5 f(x) = Cos (x) x = 45 degree

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
