17. If f = {(1,2), (2, 4), (3, 6), (4,8), (5,10)), g = {(4,9), (5, 11), (6, 13), (7, 15), (8, 17)} and (fog)-1(x) find the positive value of x. it's a optional mathematics Questions please solve him
​

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

step-by-step explanation:

the answer is 89 d
