Explanation: The range is defined as all the possible values of y. For the first function: 2^x can give a value less than 2 For example: 2^-1 = 1/2 ..........> This choice is not correct
For the second choice: 2(5^x) can also give a value less than 2 For example: 2 * (5^-1) = 2/5 ...............> This choice is wrong
For the third choice: 5^(x+2) ca also give a value less than 2 For example: 5(-3+2) = 5^-1 = 1/5 ..........> This choice is wrong
For the last option: 5^x + 2 This one will always give a value greater than 2 no matter what the value of exponent is. .......> This is the correct choice
