The function that represents an exponential growth function with a y-intercept of -1 is y = (3.5)^x - 2. The base 3.5 is greater than 1, indicating exponential growth. When x is zero, the equation simplifies to y = (3.5)⁰ -2 =1-2 = -1, which matches the given y-intercept. As x increases, the output values will grow exponentially.

Option A. y = -3x + 1

This is a linear function, not exponential.

Option C. y = y = (3)^x - 1
