Question

Substitutinginto Equations g(5)=27. Can any body please explain how the answer is 27. Thank you.

Answer 1

eqn????

Answer 2

very much

Answer 3

where is g(x) ?
is it x^2+2 ??

Answer 4

Not sure

Answer 5

there must be definations of g(x),f(x) and h(x)
somewhere, search it.

Answer 6

where is the fn G(x)???

Answer 7

g(x) = function which consists of 'x' as a variable, if u put g(5) then replace x with 5 and hence you will get the desired answer :)

Answer 8

so what is the equation really in the format:
g(x)=__________
You have to tell first what the equation is.
But whatever the equation is, you just substitute the value of x given to you which is 5 and then solve the equation from there.
This will end up giving you the answer g(5)=27

Answer 9

The question does not provide me with the equation.

Answer 10

so you have to figure out the equation.
Is that what you are saying???

Answer 11

It seems like it.

Answer 12

that is hard.
there could be several possible equations for this solution.
how can you figure out which one the question asks for?

Answer 13

It maybe a typo, I will check with my teacher monday. Thanks for the help anyways.

Answer 14

for example:
one possible equation could be:
g(x)=5x+2
so plugging the value of x that is 5:
g(5)=5(5)+2
g(5)=25+2
g(5)=27
this is only one possible solution
you can work out many of them

Answer 15

got it, Thank you!

Answer 16

@Bhagyashree if its g(x) = x^2 + 2

Answer 17

that works too
I just said there are many possible solutions or equations that you can work out from the given information
