Question

Find the range of the function r(x) for the given domain.
r(x) = 2(2*)+3
D = {-1,0,1,3}

Answer 1

Answer:  R = {4, 5, 7, 19}

Step-by-step explanation:

Domain represents the x-values.

Range represents the y-values.

Insert the values of the domain into the given equation.

$\begin {array}{c|l|c}\underline{\ x\ }&\underline{\ 2(2^x)+3 =\ }&\underline{\ r(x)\ }\\ -1&2(2^{-1})+3=&4\\0&2(2^0)+3=&5\\1&2(2^1)+3=&7\\3&2(2^3)+3=&19\\\end{array}$
