1. Does the table represent an exponential function?
Does the table represent an exponential function?
X 1,2,3,4
Y -1,-8,-27,-64
yes?
no?
No, it's just a polynomial.
y = -x^3
I agree with Steve.
I agree with Pug Lorsd who agrees with steve so the answer must be NO
To determine if the table represents an exponential function, we need to check if the y-values are obtained by repeatedly multiplying a constant factor to the x-values.
Let's calculate the ratios of consecutive y-values to the corresponding x-values:
- For the first row, the ratio is (-8) / 2 = -4.
- For the second row, the ratio is (-27) / 3 = -9.
- For the third row, the ratio is (-64) / 4 = -16.
Since the ratios are not constant, the table does not represent an exponential function.
