Answer:

f(-4) = \dfrac{1}{9}

Step-by-step explanation:

f(x) = 9(3)^x

f(-4) = 9(3)^{-4}

f(-4) = 3^2 \cdot 3^{-4}

f(-4) = 3^{-2}

f(-4) = \dfrac{1}{9}

The relation ((6, 8), (7, 10), (7, 12), (8, 16),
Brilliant_brown [7]

Answer:

x = 7 is repeated twice.

Hence, there is NO MORE unique input. We can not have repeated inputs.

Thus, the relation is NOT a function.

Step-by-step explanation:

Given the relation

  • {(6, 8), (7, 10), (7, 12), (8, 16), (10, 16)}

We know that a relation is a function that has only one output for any unique input.

As the inputs or x-values of the relations are:

at x = 6, y = 8

at x = 7, y = 10

at x = 7, y = 12

at x = 8, y = 16

at x = 10, y = 16

If we closely observe, we can check that there is a repetition of x values.

i.e. x = 7 is repeated twice.

Hence, there is NO MORE unique input. We can not have repeated inputs.

Thus, the relation is NOT a function.

Write the sum or difference in the standard form a + bi. ( 7 + 5i) - ( -9 + i)
Veseljchak [2.6K]
(7 + 5i) - ( -9 + i)
= 7 + 5i - (-9) - (i)
= 7 + 5i + 9 - i
= 16 + 4i

= 4i + 16
