Question 1188497: Given ð‘(ð‘¦) = 7𑦠+ 5, ð‘š(ð‘¦) = ð‘¦âˆ’2/5+7ð‘¦^3 and ð‘¢(ð‘¦) = ð‘¦Â² − 3.
i. Find ð‘§(ð‘¦) = ð‘(ð‘¦) − ð‘¢(ð‘¦).
ii. Find ð‘›(ð‘¦) = (ð‘ â‹… ð‘¢)(ð‘¦)
iii. Create the composite function (𑢠∘ ð‘)(ð‘¦).
iv. Evaluate ð‘(ð‘š(−2)).

iv.
\)\ =\ 7\(7y^3\,+\,y\,-\,\frac{2}{5}\)\ +\ 5)
So
\)\ =\ 7 \(7(-2)^3\,+\,(-2)\,-\,\frac{2}{5}\)\ +\ 5)
You can do your own arithmetic.
