Step-by-step explanation:
In other to draw a mapping diagram for the ordered pairs (1,0) (3,0) (5,4) (7,4) (9,4).
We identify the domain and range:
The domain is the set of the first coordinates of the ordered pairs.
Domain={1,3,5,7,9}
The range is the set of all the second coordinates.
Range: {0,4}
The exact number is 8,784 toffees but if you want me to estimate to the nearest tens then it would be 8,780
Solve for N by simplifying both sides of the equation, then isolating the variable.
N=700

7/10 is equivalent to 3.5/5 is one
f-¹(x)=
Answer:
Solution given:
f(x)=
Let f(x)=y
y=
Interchanging role of x and y
x=
doing crisscrossed multiplication
x(y+7)=-2y+2
now solve it:
xy+7x=-2y+2
keep like terms in one side
xy+2y=2-7x
take common
y(x+2)=2-7x
make a value of y
y=
So,
f-¹(x)=
