What is the value of g(−3) when g(x)=2x−2 ?
hram777 [196]

To solve a function like this, simply put the numerical value in place of the unknown variable for which you have to find the solution, for instance '-3' in this case.

g(x) = 2x-2

so to find g(-3), we just need to replace the x in the given expression by '-3'. Working is shown below:

g(x) = 2x-2

putting '-3' in place of x

g(-3) = 2(-3) - 2

g(-3) = -6 -2

g(-3) = -8
