Q. Which of the following statements about the graph of y=12(0.75)x is true?Choose 1 answer:(A) As x increases, y increases at an increasing rate.(B) As x increases, y increases at a decreasing rate.(C) As x increases, y decreases at an increasing rate.(D) As x increases, y decreases at a decreasing rate.
Analyze Function: We need to analyze the function y=12(0.75)x to determine how y changes as x increases. The base of the exponential function is 0.75, which is between 0 and 1.
Identify Exponential Decay: Since the base 0.75 is less than 1, the function represents exponential decay. This means that as x increases, the value of y will decrease.
Determine Rate of Change: Now we need to determine the rate of change of y as x increases. For an exponential decay function where the base is between 0 and 1, as x increases, y decreases at a decreasing rate. This is because each time x increases by 1, y is multiplied by the same factor of 0.75, which results in a smaller and smaller decrease in y.
Conclusion: Therefore, the correct statement about the graph of y=12(0.75)x is that as x increases, y decreases at a decreasing rate.
