Question 1039857: I need help on this I have no idea what I'm doing:
Let f (x) = 2x^2 + 8x – 5 and g(x) = 4x – 1
(a) Find the composite function (f o g)(x) and simplify the results. Show work.


(b) Find (f o g)(-1) . Show work.
Thank you so much for your guidance on this!

Fog means replace x with 4x-1
2(4x-1)^2 + 8(4x-1)-5
Now you have to replace x with -1 and you get
2(25)-40-5=5
