If f(x) = x^3 + 7x^2 – x and g(x) = x^2 – 3, what is the degree of g(f(

Here we are using f(x) as the INPUT to g(x).  

Thus, g( f(x) ) = [x^3 + 7x^2 - x]^2 - 3.  Focus on (x^3)^2.  That comes out to x^6.  The degree of g( f(x) ) is thus 6.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
