Answer:
Please check the answer below in detail.
Step-by-step explanation:
The correct form of the function is
Lets simplify
So, the function f(x) becomes
Use the exponent rule
The simplified form of the given function would be:
As domain is considered to be the set of all possible input values of x for which the function is defined.
So,
As range is the set of dependent variable for which the function is defined.
As
Therefore,

Answer:
length = 30 cm
Breadth = 10 cm
Step-by-step explanation:
Length = x cm
Breadth = (1/3)x
Perimeter = 80 cm
2(length + breadth) = 80
2* (x + (1/3)x) = 80
x = 30cm
length = 30 cm
breadth = cm
The value of f(-2) = -11.
Step-by-step explanation:
Step 1:
f(x) is dependent on the value of x. So x is independent while f(x) is dependent on x i.e. the value of f(x) depends on the value of x.
Step 2:
f(x) = 3x - 5, if we have the x's value we can calculate the f(x)'s value. Here the value of x is given as -2 so f(x) when x equals -2 can be calculated.

a)2
Step-by-step explanation:
y= 2/3x-4
y= 2/3(9)-4
y=18/3-4
y=6-4
y=2
