Question

The graph of the function g(x) is shown on the coordinate plane below. For what value of x does g(x)=0

Answer 1

The answer is -2.5 there you go

Answer 2

Answer:

Step-by-step explanation: Since you know the equation the first step is to set it equal to 0, so 1/2x+-3=0, from here you just solve using algebra, with the goal of getting x by itself.  There are three good options with one that I would say is the best.  You can multiply both sides of the equation by 2, subtract -3 from both sides or subtract 1/2x from both sides, if you don't understand that let me know.  The best I would say is subtract -3 so both sides are positive.  that leaves you with 1/2x=3.  Can you tell what to do from here?
