Stationary points occurs when the gradient of the graph is equal to 0, i.e. dy/dx = 0. Differentiate y with respect to x to get dy/dx = 4x + 4.So making 4x + 4 = 0 gives x = -1. Substituting this into the...

Procedural memories are subjected to the unconscious mind and can not be explained verbally (non-declarative) they are concerned with how to do something and not with the rules of what to do; whereas epis...

When you differentiate the function that gives the gradient. Therefore differentiate to get dy/dx= 15x^2 + 3. Make this equal to 0 to get 15x^2 + 3=0 and rearrange to get the value of x as required so 15x...

In a 1988 study, Daly and Wilson propose that marital aggression can be explained as an adaptive response. They suggest that the evolutionary desire to ensure the propagation of one's own DNA has resulted...

Answer: a(5-3a)Explanation: We take the highest common factor of both of the terms, which is a and we put it outside of the bracket. Then, in the bracket we put two terms that when multiplied by a, the pr...
