Find the inverse of the function f(x) = 7x-4/ x+3 a) this function is not one to one and therefore it has no inverse b) f^-1 (x) = -3x - 4 / x - 7 c) f^-1 (x) = x + 3 / 7x - 4 d) f^-1 (x) = 3x + 4 / x+7

we are given

function as

step-1: Set f(x)=y

step-2: Switch x and y

step-3: Solve for y

now, we can solve for y

so, we get

...............Answer

  $3150

Step-by-step explanation:

Room dimensions are each larger by a factor of 3, so the area is larger by a factor of 3×3 = 9. The cost of the carpet is expected to be ...

  9×$350 = $3150
