RE: O-Level Additional Math
hello, i would appreciate if someone can help me with these questions thanks in advance
1. Express the equation 100^x-10^(x+1)=11 as a quadratic equation in 10^x. Hence, find the value of x,correct to 2 decimal places.
2. (lgx)^2-lgx=0
3. Given y=e^(-1/2x), find the equation of the straight line in order to obtain the solution to the equation x+2lg(3x-1)=0
Thank You! -

Thank you so much! I have 1 last question
The arrow diagram shows part of the mapping h(x)=12/ax+b, xβ -b/a
Calculate the values of a and b. Hence find
(i) the element that has an image of -2 under this mapping,
(ii) the values of x for which h(x)=x
I am in sec 2 this year. and yup, i am currently doing functionshttp://i48.tinypic.com/25kq4hs.jpg\">

pls help me
The function f is defined by f(x)=1-2x.
(a) Find the range of f corresponding to the domain -1β€x<3
(b) Find the domain of f corresponding to the range 0β€f(x)<5
thanks
(a) subst x = -1 into the equation
y = 1 - 2(-1)
y = 3
Substx = 3 into the equation
y = 1 - 2(3)
y = -5
Thus, the range of f is : { y: -5 < y β€ 3}
(b) qn means that: find the range of values of x such that f(x) = 0
1 -2x = 0
2x = 1
x = 0.5
1 - 2x = 5
2 x = -4
x = - 2
{x : -2 < x β€ 0.5 }
Note: The domain of the function refers to the x value while the range of the function refers to the y value.
:thankyou:
i have another question
The diagram shows the graph of the curve y=4/x-1 for x>1
With the aid of the graphhttp://i47.tinypic.com/2w6w4sk.jpg\"> , find
(a) the range of f(x)=4/x-1 for the domain 2<x<5,
(b) the domain of f defined by f(x)=4/x-1 corresponding to the range 1<f(x)<3. -
