Sorry if i posted this in the wrong section.
In the attachment, i posted a photo of what i need help with.
As you will see (if the photo actually works..) the first part says y=ax².
I had to substitute numbers in for a, which were a=-2, -1, -1/2, 1/2, 2, 3.
Which i did using a computerised calculator (fx9860emulator) and graphed it. The graph attachment is also there...
anyway, my problem is, it says "Complete a similar style of investigation for the quadratic functions below:
- y=x² + c
- y=x² + bx
- y=(x-h)² + k
- y=ax² + bx + c
Hint: keep 2 of the values (a,b or c) constant and look at the effect of changing the other.
So, am i mean't to substitue random numbers into the letters c, bx and such? or do i use the same formula that a used?
