Give the value of fx) in each of the following cases. Please write legible. Write appropriate units in the answers.
1) f ( x ) = x n ,   x = 4 , n = 2
2) f ( x ) = ln x ,   x = 10
3) f ( x ) = log a ( x ) ,   x = 238 , a = 2
4) f ( x ) = 1 / x , x = 3
5) f ( x ) = e x , x = 15
6) f ( x ) = | x | , x = 10
7) f ( x ) = a x , x = 4 , a = 2
8) f ( x ) = sin x , x = 0.75   r a d i a n s
9) f ( x ) = arcsin x , x = 0.5
10) f ( x ) = cos ( x ) , x = 45 .
1. Understand degrees ( )
π radians=180 degrees
3.14 radians=180degrees
1 radian = 180 / 3.14 degrees.
2. Understand how to change the base of logarthemic expression.

Step 1
1) f ( x ) = x n , x = 4 , n = 2
= ( 4 ) 2
= 1 ( 4 ) 2 = 1 16
2) f ( x ) = ln x = ln ( 10 ) = 2.30258509
3) f ( x ) = 109 a ( x ) = 109 2 ( 238 )
= 7.894817763
Step 2
4) f ( x ) = 1 / x , x = 3
= 1 3 = 1 3
5) f ( x ) = e x , x = 1.5
= e ( 1.5 )
= 0.22313016
6) f ( x ) = | x | , x = 10
= | 10 | = 10

Step 1
7) f ( x ) = a x , x = 4 , a = 2
= 2 4
= 16
8) f ( x ) = sin x , x = 0.75 r a d i a n s
Step 2
9) f ( x ) = arcsin ( x ) , x = 0.5
= arcsin ( 0.5 )
= 0.523598776 r a d
