10 Page 3 of sFind (fog)x) when f(x) 5x 1 and g(x) x 4 9. Evaluate logs (789) and round your answer to 4 decimal places. 10. Write an equation for a function whose graph fits the given description. The graph of f(x)x isshifted 3 units to the left and then shifted 7 units upward. 11, Find the radius of the circle given by the equation x2 + y2-6x-27 0

Solution

8) f(x) = 5x +1

g(x) = x- 4

(fog)(x) = 5(x-4) + 1

= 5x - 20 + 1

= 5x -19

(fog)(x) = 5x - 19

9) log ₅ ( 789 / 42 )

= log 789/42 / log 5

= 1.8224
