Question

Write an exponential function represented by the table

X | 0 | 1 | 2 | 3 |
Y | -50 | -10 | -2 | -0.4 |

Answer 1

50-10-2-4=34 RESPONS Y

Answer 2

• y = -50(1/5)^x

Explanation:

Exponential function:

• y = ab^x

As per the table we have:

• The initial value is -50 at x= 0
• Common ratio is 1/5

Considering the above, a = -50, b = 1/5

The function is:

• y = -50(1/5)^x
