Question

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

Answer 1

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

Answer 2

you got the last step?

Answer 3

no its difficult can u explain

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

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