what are the missing numbers?
crimeas [40]

Given:

The table of values of an exponential function.

To find:

The missing values in the exponential function.

Solution:

The general exponential function is defined as:

y=a(b)^x              ...(i)

Where, a is the initial value and b is the growth factor.

First point from the given table is (1,10). It means, the equation (i) must be true for (1,10).

10=a(b)^1             ...(ii)

Second point from the given table is (2,20). It means, the equation (i) must be true for (2,20).

20=a(b)^2             ...(iii)

Dividing (iii) by (ii), we get

\dfrac{20}{10}=\dfrac{a(b)^2}{ab}

2=b

Putting b=2 in (ii), we get

10=a(2)^1

\dfrac{10}{2}=a

5=a

Putting a=5,b=2 in (i), we get

y=5(2)^x

The required exponential function for the given table of values is y=5(2)^x. So, the missing values are 2 and x, where 2 is in the base and x is in the power.
