Using a table of values, determine the solution to the equation below to the nearest fourth of a unit. 2^(-x) -2=4^x -1

I think letter C.x*-0.50 I'm not sure In my answer

1/4 because there is 4 grades.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
