This table shows the input and output values for an exponential function f(x) . What is the ratio of outputs for any two inputs that are one value apart?

that just means to divide [tex]f(x_n)[/tex] by [tex]f(x_{n-1})[/tex]
pick any 2 consecutive points and divide the y value of the one with the higher x value by the other y value
x=0 and x=1
-1 and -2
-2/-1=2
ratio is 2
Answer:
2
Step-by-step explanation:
A ratio is a comparison of two numbers by division.
Taking the first two outputs, -1/8 and -1/4, we divide the second one by the first one to find the ratio:
-1/4 ÷ -1/8
When dividing fractions, we multiply by the reciprocal:
-1/4 × -8/1
To multiply fractions, multiply straight across:
(-1×-8)/(4×1) = 8/4 = 2
