Microsoft Excel help (Hardcore!)?

Question

Help I dont know how to do this. The X (column A) is a random number.

Calculate y, (column B) based on the x value listed in column A. If 0 ≤ x ≤ 3, then y = 2x. If 3 < x ≤ 10, then y = (x-3)2 + 6. If x < 0, note "negative x". If x >10, note "x is too large".

Answer 1

had ot break it up into 3 lines, but it should be 1 formula

=IF(A2<0,"negative x",(IF(A2<4,+
A2*2,IF(+A2<11,
+(+A2-3)*2+6,"x is too large"))))
