Question

Use the equation and type the ordered-pairs. y = 2^x {(-1, ), (0, ), (1, ), (2, ), (3, ), (4, )}

Answer 1

Put the values of x to the equation y = 2ˣ:

`x=-1\to y=2^(-1)=(1)/(2)\to\left(-1,\ (1)/(2)\right)\\\\x=0\to y=2^0=1\to(0,\ 1)\\\\x=1\to y=2^1=2\to(1,\ 2)\\\\x=2\to y=2^2=4\to(2,\ 4)\\\\x=3\to y=2^3=8\to(3,\ 8)\\\\x=4\to y=2^4=16\to (4,\ 16)`

Answer:

`\left\{\left(-1,\ (1)/(2)\right);\ (0,\ 1);\ (1,\ 2);\ (2,\ 4);\ (3,\ 8);\ (4,\ 16)\right\}`
