I can't understand what A and B is asking me. They want me to insert 0 for x? Then what?

welshfella · Answer

0 is < 1  so which function do you use?

jh99 · Answer

Is this asking me is I should use a linear function?

welshfella · Answer

check  the function in the question  - which one is to be used for finding f(0)   - is it x^2  or 
2x + 1?

jh99 · Answer

I think x^2?

welshfella · Answer

yes  right

so replace  x by 0  in x^2 and you'll get the answer.

welshfella · Answer

- the answer to B.

welshfella · Answer

the answer to A is x^2
