Which steps should be used to graph the equation y-4=1/3 (x+2)

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x

Is experimental probibilty the same as the observed frequency in math? i need the answer asap!
