Hi, I need help with these three questions please

The function f(x) = 'Vx is one-to-one. a. Find an equation for f (x), the inverse function. b. Verify that the equation is correct by showing that f (f (x)) = x and f (f(x)) =x. a. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. f ( X ) = for x 20 OB. f ( X ) = for all x O c. f( x ) = , for x SO b. Verify that the equation is correct. F ( F - 1 ( x ) ) = $ ( [ and F - 1 (f( x ) ) = f - 1 () Substitute. and Simplify. The equation isThe functions f and g are graphed in the same rectangular coordinate system, shown to the right. If g is obtained from f through a sequence of transformations, find an equation for g. g(x) f(X) = VX 10 What is the equation for g? g(x) =Write the slope-intercept equation of the function fwhose graph satisies the given conditions. The graph off passes through (- 6,7) and is perpendicular to the line that has an x-intercept of 4 and a y-intercept of - 8. The equation of the function is D. (Use integers or fractions for any numbers in the equation.)
