Answer 2

Finding the Range of the Function

To find the range of the function \( u = 2x + 5 \) for \( 1 \leq x \leq 3 \), we can start by determining the values of \( u \) for the given range of \( x \).

First, let's find the value of \( u \) when \( x = 1 \): \[ u(1) = 2 \times 1 + 5 = 7 \]

Next, let's find the value of \( u \) when \( x = 3 \): \[ u(3) = 2 \times 3 + 5 = 11 \]

So, the range of the function \( u = 2x + 5 \) for \( 1 \leq x \leq 3 \) is 7 ≤ u ≤ 11.

This means that the function \( u = 2x + 5 \) will produce values between 7 and 11 for the given range of \( x \) values.
