we know thatif the exponential function passes through the given point, then the point must satisfy the equation of the exponential functionwe proceed to verify in each case whether the point is satisfied for the exponential function case To calculate the value of y in the equation and, then, compare with the y-coordinate of the pointsothereforethe exponential function does not pass through the point of case B To calculate the value of y in the equation, and then compare with the y-coordinate of the pointsothereforethe exponential function passes through the point in the case C To calculate the value of y in the equation and, then, compare with the y-coordinate of the pointsothereforethe exponential function does not pass through the point case D To calculate the value of y in the equation and, then, compare with the y-coordinate of the pointsothereforethe exponential function passes through the point thereforethe answer is
