For the following curves i) y=x^2+4x-1 ii) y=-2+or-Square root(x+5)(adsbygoogle = window.adsbygoogle || []).push({});

a) Sketch both the curves on the same sheet of graph paper- against the same axis

I have done this, although I have not shown it here

b) Determine with proof, whether the above curves are related.

Not sure how to do this.

c)Determine with proof, if either of the above curves are a function

Not sure how to do this either.

d)Determine, with proof, whether either of the curves displays odd or even symmetry

y=f(x)=x^2+4x-1

f(-x)=-x^2+4x-1

Even function

Is this correct

Any help would be great thanks
