Step-by-step explanation:
Because the minimum value of f(x) is -1, and the minimum value of g(x) us -25. It comes only once.
Roots are the points on the x - axis or when the x is 0. The roots of f(x) are positive.
f(0) means when x is 0, so f(0) = 3 or 5, and g(0) = -24

assume f is a one to one function of f(x)= 4-6x find f^-1(-32)
Answers
Answer:
f^-1(-32)=6
Step-by-step explanation:
Find the inverse of the function f(x)=4-6x:
f(x)=4-6x
y=4-6x
x=4-6y
x-4=-6y
(x-4)/-6=y
-1/6x+2/3=y
y=-1/6x+2/3
f^-1(x)=-1/6x+2/3
Plug in f^-1(-32) for f^-1(x) and simplify:
f^-1(-32)=-1/6(-32)+2/3
f^-1(-32)=16/3+2/3
f^-1(-32)=18/3
f^-1(-32)=6

f(-2) = -3 - 4
f(-2) = -7
Answer:
f(-2) = -7
Step-by-step explanation:
f(-2) means that for every x given in the equation, -2 would be substituted in it's place. Therefore;
