[3.07] Choose the best description of how to calculate f[g(−4)] if f(x) = 2x + 1 and g(x) = x2 − 10.

Question

anonymous · Answer

that was wrong sorry
first compute 
$$g(-4)=(-4)^2-10=16-10=6$$ then compute $f(6)$

anonymous · Answer

you got the last step?

anonymous · Answer

no its difficult can u explain

anonymous · Answer

first i replaced $x$ by $-4$ in the function $g(x)=x^2-10$

anonymous · Answer

just make the replacement, make sure to use parentheses
so i got $g(-4)=(-4)^2-10=(-4)\times (-4)-10=16-10=6$

anonymous · Answer

then we we have to replace $x$ in $f(x)=2x+1$ by 6 to get 
$$f(6)=2\times 6-1=12-1=11$$
then we are done

oooh now i get it  so much easier when you explain it to me

hope it helped, i don't think i skipped any steps
