This is a function which is in the form, 

y = f(x)g(x)

It's the product of two functions and so we must make use of the product rule. This i...

To differentiate x^2

Step 1) whatever the number on the power, put that in front of x. 

Step 2) Then minus one (-1)  from the power

Therefore, by putting the n...

(1) 2x - 5y = 11(2) 3x + 2y = 7-----------------------Multiply equation (1) by 3 & Multiply equation (2) by 2 to give equal values for x:(3) 6x - 15y = 33(4) 6x + 4y = 14-----------------------Take eq...

We know that a straight line has a general formula: y = mx+c, where m is the gradient of the line and c is the y-intercept; so, we are looking to find m and c. 

The line passes through th...
