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

Question

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

Answer 1

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 \(585\).
