F(x) = 3x + 2x = 3f-1(x) + 2x - 2 = 3f-1(x)(x - 2)/3 = f-1(x)(14 - 2)/3 = f-1(14)12/3 = f-1(14)4 = f-1(14) f(f-1(14)) = f(4)f(4) = 3(4) + 2f(4) = 12 + 2f(4) = 14 A function and its inverse are inverse operations, like addition and subtraction. They undo each other. f(f-1(x) = x
Answer:
-5
-11x+2
Step-by-step explanation:
-4
-6x-1--5x+3=-5-11x+2
Answer:
49
Step-by-step explanation:
x = 7
1 / x^-2
= x^2
= 7^2
= 49
Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3
X less than or equal to (< with the line underneath) -3 or x>0
