Help me please !!!!!!!!

y=5/3x

this is because f(x)=x is one of (identity function) the 12 basic functions and when you multiply it it will shift it on the y axis

If you were to do y=x+5/3 it would make a horizontal shift to the left 5/3

So the unit your on is mostly about knowing the number located in the function that will make the graph shift different ways

Answer:

41. f⁻¹(x) = -9x + 4

43. m⁻¹(x) = ∛(x-2)/4  

Step-by-step explanation:

41. y = (4-x)/9

swap x and y: x = (4-y)/9

solve y: 9x = 4-y

             y = -9x + 4

45. y = 4x³+2

     x = 4y³+2

     4y³ = x-2

     y³ = (x-2)/4

     y = ∛(x-2)/4

Let you do 42 and 46 by yourself
