Question
49. Which of these are not exponential relations? State reasons for all of your choices.
y = -2/3x - 2
y = 3 (x in place of square)
y = x²
y = -(x + 2)²
y = -2/3x - 2
y = 3 (x in place of square)
y = x²
y = -(x + 2)²

well, exponential functions are of the form y = a^x
where a is some positive number.
The "^" indicates an exponent when typing online

y = 3^x is exponential.That means the variable, in this case x, is in the exponent, not in the base. Thus y = x ^ 3 is NOT an exponential function.
