State
a) the relation in the form of ordered pairs
{(2,6),(3,9) n so onn . uat sndrik hahahha
b)the type of relation
one to one
c)the range
{6.9,18,21}
d)the image of 6

2.Given that g(x)=2x+1/ x-3 , x /=p .find ( x/p mknenyer not equal)
a)the value of p
p=3
b)the value of g(5)
11/2
c)the value of x such that g(2x)= -2
5/8

3.Without using the calculator,find the value of the following:
a) (4)^3/2 + log5 125
=11
b) log3 27 + logy /y (square root)
=3+1/2

4.Given that logm 2=p and logm(27m/4) in terms of p and r
= 3r-2p+1

5.Solve the equation 2 + log3 (x-1) = log3 x
x= 9/8

6.Solve the following equations
a)log2 y = 0
y =1
b)32^4x = 4^8x+6
=3

SECTION B

7.Simplify each of the following
i) a) (16p^6)^1/2
= 4p^3
b) 4^n+1 x(drb) 2^n divide 8^3n
= 2^-6n+2

ii) using the laws of logarithms , evaluate log3 5 + 2log3 4 - log3 80
= log3 1 = 0

8. a) Solve the following equations
i) log16 x = 1/2
x = 4
ii) 2^x+4 - 2^x+3 =1
x= -3

b)Solve the equation 3^x+2= 7. Give ur answer correct to 4significant figures
= -0.2288

9. a) Given that log3 R -log9 Q=2 , express Q in terms of R
R^2/Q = 9^2
