Answer:
a = -2
Step-by-step explanation:
g(x) = 3/2x + 3
g(a) = 0
g(a) = 3/2a +3 =0
Subtract 3 from each side
3/2a +3-3=0-3
3/2a = -3
Multiply each side by 2/3
2/3 * 3/2a = -3*2/3
a = -2
Negative rate of change just means the graph is falling. This one is falling everywhere after x=0.5. The only choice in that section of the graph is the last one.
I think is would be $25.04. I'm sorry if i get this wrong. I am only a middle schooler. Sorry if this didn't help.<span />
