What is 3x66 as a logarithmic function?
log (3 x 66) = log 3 + log 66
Explain why a and b must be equal if log a equals log b?
It is because the logarithm function is strictly monotonic.
What is the inverse of the function y equals log 5 x?
log5x
What is the domain of the natural log function?
The domain of y=lnx is (0,∞) and the range is (-∞,∞).
When you log transform a power function the resulting function is a straight line?
Yes, the resulting function is a straight line. This is the source:http://www.mathbench.umd.edu/mod207_scaling/page10.htm
What is 3x66 as a logarithmic function?
log (3 x 66) = log 3 + log 66
Is log n considered a polynomial function?
No, log n is not considered a polynomial function. It is a logarithmic function, which grows at a slower rate than polynomial functions.
How do you use inverse log on graphing calculator?
The inverse of a logarithmic function is an exponential function. So to find the "inverse" of the log function, you use the universal power key, unless you're finding the inverse of a natural log, then you use the e^x key.
Inverse logs on TI-83 plus?
To get the inverse log function, press 2ND and then choose 10x. (Above LOG.) To get the inverse of a natural log function, press 2ND and then choose ex. (Above LN.)
How do you calculate Log2 in Excel?
Use the LOG function. =LOG(n,b) n = Number b = Base =LOG(2,10) = 0.30103
Explain why a and b must be equal if log a equals log b?
It is because the logarithm function is strictly monotonic.
How do you find the inverse log using a TI 84 plus?
The 2nd function of the log button is the inverse log. Press 2nd log, which displays 10^( on the screen. Put a number after the opening parenthesis.
How do you do an inverse log on a TI 30x?
On the TI-30x model there is no INV button. You have to use the 10^x function. To do this press the button labeled "2nd" and then the button labeled LOG. Above the LOG button you should see the 10x function which is the same for INV.
What is the inverse of the function y equals log 5 x?
log5x
What is the relationship between the growth rate of a function and the shape of an n log n graph?
The growth rate of a function is related to the shape of an n log n graph in that the n log n function grows faster than linear functions but slower than quadratic functions. This means that as the input size increases, the n log n graph will increase at a rate that is between linear and quadratic growth.
What is the domain of the natural log function?
The domain of y=lnx is (0,∞) and the range is (-∞,∞).
Give an example of an exponential function Find this exponential function's inverse which will be a logarithmic function Plot the graph of both the functions?
An exponential function can be is of the form f(x) = a*(b^x). Some examples are f1(x) = 3*(10^x), or f2(x) = e^(-2*x). Note that the latter still fits the format, with b = e^(-2). The inverse is the logarithmic function. So for y = f1(x) = 3*(10^x), reverse the x & y, and solve for y:x = 3*(10^y)log(x) = log(3*(10^y)) = log(3) + log(10^y) = log(3) + y*log(10) = y*1 + log(3)y = log(x) - log(3) = log(x/3)The second function: y = e^(-2*x), the inverse is: x = e^(-2*y).ln(x) = ln(e^(-2*y)) = -2*y*ln(e) = -2*y*1y = -ln(x)/2 = ln(x^(-1/2))See related link for an example graph.
