Using Logarithmic Graphs Flashcards
1
Q
How is the model y = ax^n expressed in the form Y = mX + c (linear form)?
A
log(y) = log(a) + nlog(x)
2
Q
For the model y = ax^n how do you plot the graph?
A
Log(y) is plotted on the y-axis and log(x) is plotted on the x-axis.
3
Q
For the graph of log(y) against log(x), what is the gradient of the straight line?
A
n
4
Q
For the graph of log(y) against log(x), what is the vertical intercept?
A
log(a)
5
Q
How is the model y = ab^x expressed in the form Y = mX + c (linear form)?
A
log(y) = log(a) + xlog(b)
6
Q
For the model y = ab^x how do you plot the graph?
A
Log(y) is plotted on the y-axis and x is plotted on the x-axis.
7
Q
For the graph of log(y) against x, what is the gradient of the straight line?
A
log(b)
8
Q
for the graph log(y) against x, what is the vertical intercept?
A
log(a)
