The function f(x) is graphed below. What is the equation of the line that is perpendicular to f(x) and passes through the point (4, –6)? 4x + 3y = –2 3x + 4y = –12 4x – 3y = 34 3x – 4y = 36

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
