suppose g(x)=1/2x-1. Find each value.
then i have to plug in 3g(4). I know the answer i just need to know how to get to it....plz help!
Put 4 where the "x" is in the g(x) formula, and then muytiply the result by 3.
omg thnx
The way you wrote the problem, it isn't clear if g(x) =
1/(2x) - 1 or 1/(2x-1)
They are not the same.
To find the value of g(x), which is given by the equation g(x) = 1/2x - 1, you need to substitute the value of x into the equation.
In this case, you are asked to find 3g(4), which means you need to substitute 4 into the equation and then multiply the result by 3.
To find g(4), substitute x with 4 in the equation:
g(4) = 1/2(4) - 1
= 2 - 1
= 1
Now, multiply the result of g(4) by 3 to find 3g(4):
3g(4) = 3 * 1
= 3
Therefore, the value of 3g(4) is equal to 3.
