Complete the input output table for the function y=3^x
egoroff_w [7]

Answer:

Input of x when it is equal to (1,2,3,4,5) gave an output of 3, 9, 27,81 & 243 respectively.

Step-by-step explanation:

Step 1. Substitute for x (1,2,3,4,5) in the functions to solve for the output of y.

y=3^x

when x= 1

y=3¹ = 3

when x= 2

y=3² = 9

when x= 3

y=3³ = 27

when x= 4

y=3⁴ = 81

when x= 5

y=3 ^ 5 = 243.

Input of x when it is equal to (1,2,3,4,5) gave an output of 3, 9, 27,81 & 243 respectively.

kiruha [24]

Answer:

\frac{1}{4} of the books in the book store are mystery fiction books.

Step-by-step explanation:

Let x represent all the books in the books store.

Then, the fraction of books that are fiction books is \frac{3}{4}x

We have that; \frac{1}{3} of the fiction books are mystery books.

The fraction of the books at the  bookstore that are mystery fiction  books is \frac{1}{3}\times \frac{3}{4}x=\frac{1}{4}x.

Therefore \frac{1}{4} of the books in the bookstore are mystery fiction books.
