okay i did

phi · Answer

So this question is really trying to teach you something.  It is not hard.

anonymous · Answer

k

phi · Answer

The y intercept happens when x=0.  So plug x=0 into each equation, to find f(0) which will be the y intercept

anonymous · Answer

can u write it out

phi · Answer

Try this one
f(x)=-(x-3)(x+5)

replace x with a 0
f(0)= -(0-3)(0+5)
can you do the arithmetic?
