Question

Given the function g(x) = −2x + 4, find g(−5).

Answer 1

substitute the -5 where ever you see an x

Answer 2

so it would be
g(-5) = -2(-5) + 4
then simplify

Answer 3

can you do it from here?

Answer 4

-5g=-10+4
divide all by 5 right?

Answer 5

g(x) is a function..

You cannot write it as : xg


You have to write in g(x) form..

So when you plug x = -5 here:

It will remain like this:

\(g(-5)\)..

Answer 6

Can you tell me the value for this:

\(-2(-5) = ??\)

Answer 7

my bad... 10

Answer 8

So what will be the value now can you tell ??

Answer 9

\[g(-5) = -2(-5) + 4 = ??\]

Answer 10

-5g=10+4

Answer 11

I said to leave that in g(-5) form..

You will not do anything with left hand side..

g(-5) will remain as it is..

Why are you not adding 10 and 4 ???

Answer 12

ohh ok and idk i added them together in my head.

Answer 13

So what is the value for \(g(-5)\) ??

Answer 14

wouldn't it be g(-5)?

Answer 15

Yes..

What I have written ??

Answer 16

g(-5)=14 so how would d i solve this?

Answer 17

You have solved this..

This is what question wants from you..
g(-5) = 14

is the answer dear..

Answer 18

well now it makes sense... i didn't understand the question.

Answer 19

thank you
