There is one on-line at: http://www.calculatorsoup.com/calculators/math/fractions.php
.
You need to specify the function that you want graphed in that domain and range.
Try the calculator here: http://www.socscistatistics.com/tests/ztest/
\(\frac{m-2}{m+2}-\frac{m+2}{m-2} \rightarrow\frac{(m-2)^2-(m+2)^2}{m^2-4}\\ \rightarrow \frac{m^2-4m+4-m^2-4m-4}{m^2-4}\rightarrow-\frac{8m}{m^2-4}\)
Example:
f(x) = x
(f(4) - f(2))/2 = 1
But the slope of f(x) is 1 everywhere, so for any c the value of f'(c) will equal (f(4) - f(2))/2
Melody is correct.
Oops! The last number should be 5*10^-7m^2
1mm = 10^-3 m
1mm^2 = 10^-6 m^2
0.5mm^2 = 0.5*10^-6 m^2 → 5*10^-5 m^2
Like so:
Use Pythagoras: horizontal distance = sqrt(hypotenuse^2 - height^2)
4x+10=-26 Subtract 10 from both sides
4x = -36 Divide both sides by 4
x = -9
