Question

. Given the rule y = 2x +1. Find the rang

Answer 1

Answer:

1. Range: $\infty < y < \infty$

2.  {(1,3), (2,6),(3,9)}

Explanation:

Solving (1):

Given

$y = 2x + 1$

Required: Determine the range

For every value of x, there is a corresponding y value.

This implies that, the domain is:

$\infty < x < \infty$

And the corresponding range is:

$\infty < y < \infty$

Solving (2): Determine which of the options is a relation.

Option (c) is a relation because it has domain (x) and range (y) and can be represented as:

$(x,y)=\{(1,3), (2,6),(3,9)\}$
