If f(x) =2x/7+4 ,which of the following is the inverse of f(x)?

a. f¹(x)=2(x+4)/7
b. f¹(x)=2(x-4)/7
c. f¹(x)=7(x-4)/2
d. f¹(x)=7(x+4)/2

Step-by-step explanation:

f(x) = (2x / 7) + 4change f(x) to y

y = (2x / 7) + 4switch ur x and y and solve for y

x = 2y/7 + 4subtract 4 from both sides

x - 4 = 2y/ 7multiply by 7

7(x - 4) = 2ydivide by 2

7(x - 4) / 2 = y answer C

d

step-by-step explanation:

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
