Question

Which exponential equation contains the points (−1,5) and (2,5000)? (1 point) Responses

y=(500)x
y is equal to 500 to the x th power

y=50⋅−(10)x
y is equal to 50 times negative 10 to the x th power

y=−50⋅(10)x
y is equal to negative 50 times 10 to the x th power

y=50⋅(10)x
y is equal to 50 times 10 to the x th power

Answer 1

y = 50·(10)^x

Check: For x = −1: y = 50·10^(−1) = 50·0.1 = 5. For x = 2: y = 50·10^2 = 50·100 = 5000.
