Area of a triangle= bh/2b=4in h=8in8x4/2=16in
there are 4 triangles
4x16=64
area of a rectangle=bh
4x4=16
64+16=80in^2
Answer:
Option B
Step-by-step explanation:
Domain of a function is the set of x-values or input values.
Similarly, Range of a function is the set of y-values of output values.
From the graph attached,
Function is defined for all x-values (For all real numbers).
Therefore, domain of the function is {x | x ∈ R}
Option B will be the answer.
