g(x)=10/4-7x

do you mean f(x)?

and are you trying to find the zero of the function? if you are then:

f(x)=10/4-7x
0=10/4-7x
-10/4=7x
-5/14 is your answer.

To find the value of g(x) for a given x in the function g(x) = 10/(4 - 7x), let's work through the steps:

Step 1: Start with the given function:
g(x) = 10/(4 - 7x)

Step 2: Substitute the value of x into the function. For example, if you want to find g(2), substitute x = 2:
g(2) = 10/(4 - 7(2))

Step 3: Simplify inside the parentheses:
g(2) = 10/(4 - 14)

Step 4: Continue simplifying:
g(2) = 10/(-10)
g(2) = -1

Hence, g(2) = -1.

You can follow the same steps to find g(x) for any other value of x by substituting it into the function and simplifying the expression.
