Which of the following equations would be set up to solve in the graphing calculator as described below? y1=7^-3x;y2=6 Find where the graph of y1 is above the

Question

graph of y2

 

1. 7^-3x>6

2. 7^-3x<6

3. 7^-3x>=6

4. 7^-3x<=6

Answer 1

y₁ = 7^-3x

y₂ = 6

 

y₁ > y₂ ⇒ 7^-3x > 6

Answer (1) is correct.
