Need help as soon as possible solving questions 7, 9, 10, and 12 in the first image, and just number 7 in the second image.

7. Determine the equation of the transformed y = x* function that has an minimum at (-2,5) and a y-intercept of 58 _ ) 5 8. Given /(x ) = ] -+4 is a transformation of a parent function, g(x), determine the: 6 x - 1 a) equation of the parent function g ( x ) = _= b) domain of f(x) 60 - 1 70 620 7 1 c) range of f(x) 9. Given f(x) = -3(2x -10)* + 243 determine the: a) x-intercepts, if any b) range of f(x) MER UE 2435 c) coordinates of any turning points (max/min) 2 ( DC - S ) ( 15, 243 ) d) interval(s) of decrease DC = 15 10. Simplify g(x) = 5-2x+24 -6 so g(x) has no horizontal stretch/compression, 11. If (x, y) - (2x -5,-7y+3) is the mapping rule for a transformation of y = vx then state the equation of the transformed function. y = - 7 1 2 ( 2 + 5 ) + 3 12. The domain of g(x) is (x ER|x > -5; and its range is (9(x) ER|-14 sg(x) x neither neither -10 10 c) coordinates of -5 + all turning pts (max/min) (-4.3.-9.5) d) end behaviour as x -> co -10 - /18All answers should be expressed ! act values unless otherwise specified. 1.
