Simultaneous equations have at least two unknowns that must have the same value in each equation. This means the value of x and y in both equations must...
From previous question y=2(x+2)2-1Minimum would be when (x+2)2 is at it's smallest value, in this case when (x+2)=0 since any other value squared would be greater than 0. This occurs...
2x2+8x+7=2(x2+4)+7=2((x+2)2-4)+7=2(x+2)2-8+7=2(x+2)2-1A=2, B=2, C=-1
Start again by drawing the graph and then the translated graphExplain what is meant by a translation ( a movement of the graph )Use a table of values to show how we can change the function to allow for di...
Start by drawing an example graph which contains stationary points, use this to explain what a stationary point is. Explain how we could manipulate the graph to identify these points (explaining different...
