Question

If h(x) = 3x − 1 and j(x) = −2x, solve h[j(2)] and select the correct answer below.

Answer 1

−11
11
−13
13

Answer 2

hmm, what's J(2) anyway?

Answer 3

@zepdrix @mathmate

Answer 4

j(2)=j(x) x=2. @jdoe0001

Answer 5

well,, j(x) = -2x so if x = 2 that means j(2), then j(2) = ?

Answer 6

-4

Answer 7

yeap so now we know that j(2) = -4
thus \(\bf h({\color{brown}{ j(2)}}\iff h({\color{brown}{ -4}}=-3({\color{brown}{ -4}})-1\)

Answer 8

okay so -4=11

Answer 9

hmm \(\bf h({\color{brown}{ j(2)}})\iff h({\color{brown}{ -4}})=-3({\color{brown}{ -4}})-1
\\ \quad \\
h(j(2))=-12-1\implies h(j(2))=-13\)

Answer 10

so c, -13? Thanks for the help. Can you help with one more?

Answer 11

hmm actually have a typo, is 13 no -13 but anyhow \(\bf h({\color{brown}{ j(2)}})\iff h({\color{brown}{ -4}})=3({\color{brown}{ -4}})-1
\\ \quad \\
h(j(2))=-12-1\implies h(j(2))=-13\)

Answer 12

sure, post anew, thus more eyes

Answer 13

so 13

Answer 14

not -13

Answer 15

3* -4 = -12
-12 - 1 = -13

Answer 16

so the answer is -13?

Answer 17

well... the answer is \(\bf h({\color{brown}{ j(2)}})\iff h({\color{brown}{ -4}})=3({\color{brown}{ -4}})-1
\\ \quad \\
h(j(2))=-12-1\implies h(j(2))=-13\) :)

Answer 18

but its multiple choice, so h(j(2))=-13

Answer 19

thanks!
