Answer:

Step-by-step explanation:
Let the exponential function be

We substitute (0,9) to get:



The equation now becomes:

We substitute (3,72) to get:



The equation is therefore

(6,8) i think that is the correct answer.
(5x+1)² = 7; expand: 25x² + 10x +1 = 7 or 25x² + 10x -6 = 0
Solve this quadratic for x:
x = [-b + √(b² - 4ac)]/2a and x = [-b - √(b² - 4ac)]/2a
Plug the values and you'll find :
x = (- √7 - 1)/5 (answer C)
x = (+√7 -1)/5 (answer E)
