Three classmates are working with three different expressions. Each classmate substitutes in the value x=4

into their expression.

Eleanor Parker Nellie
5x−10
5x^2+3
5^x−40
When substituting in the value x=4
, Eleanor would get a result of Response area, Parker would get a result of Response area, and Nellie would get a result of Response area



Response areaexpression produced the largest value

Let's evaluate each expression by substituting \(x = 4\) into each one.

1. **Eleanor's expression: \(5x - 10\)**
\[
5(4) - 10 = 20 - 10 = 10
\]

2. **Parker's expression: \(5x^2 + 3\)**
\[
5(4^2) + 3 = 5(16) + 3 = 80 + 3 = 83
\]

3. **Nellie's expression: \(5^x - 40\)**
\[
5^4 - 40 = 625 - 40 = 585
\]

Now we can summarize the results:

- Eleanor: \(10\)
- Parker: \(83\)
- Nellie: \(585\)

Thus, the expression produced the largest value is Nellie's expression: \(5^x - 40\), which yields \(585\).
