Question 302792
1a. What system of equations could you enter on your graphing calculator
 to solve the exponential equations 6^(x-1)= 7
Subtract 7 from both sides
6^(x-1) - 7 = 0
 y = 6^(x-1) - 7
:
1b. Use your system of equations and your graphing calculator to solve the
 exponential equation given in question 1.
Enter into y=: 6^(x-1)-7
Select: calc 2:Zero feature, x = 2.086
