Answer:
True.
Step-by-step explanation:
For example let f(x) = 3x + 1 then f-1(x) is found as follows
Let f(x) = y = 3x + 1 then
3x = y - 1
x = (y-1) / 3
x = f-1(x) = (x - 1)/3.
So:
Replacing the x in y by (x - 1)/3 :-
x = f(-1)(y) = ( (3x + 1) - 1) / 3
= 3x / 3
= x.
So y = f(x).

Step-by-step explanation:
8/16=0.50
Answer:
A
Step-by-step explanation:
since the slope (2) is positive the graph is similar to y=x, so graphs B and D are eliminated
so when x=1 we have
y=2(1)-3
y=2-3
y=-1
so the point is (1,-1), graph C eliminated
so it's A
Lets create both equations and :
f(x) = 5x^2 + 1
linear binomial form: x - 4
according to the remainder theorem, x - 4 is a divisor of f(x) if and only if f(4) = 0
f(4) = 5*16 + 1 = 81
hence x - 4 is not a divisor of f(x)
