  • H=9ft
  • B=6ft

Using Pythagorean thereon

\\ \Large\sf\longmapsto P^2=H^2-B^2

\\ \Large\sf\longmapsto P^2=9^2-6^2

\\ \Large\sf\longmapsto P^2=81-36

\\ \Large\sf\longmapsto P^2=45

\\ \Large\sf\longmapsto P=\sqrt{45}

\\ \Large\sf\longmapsto P=6.3ft

Which graphs below have a domain of all real numbers? Which have a range of all real numbers? Which are functions?
slava [35]

Answer:

Step-by-step explanation:

From the picture attached,

Graph (A)

Domain of the function : (-∞, ∞) or a set of real numbers

Range of the function : (-∞, ∞) or a set of real numbers

Graph (B),

Domain : (-∞, ∞) Or a set of real numbers

Range : (-∞, 6] Or x ≤ 6

Graph (C),

Domain : [-2, ∞) or x ≥ -2

Range : (-∞, ∞) Or a set of real numbers

Therefore, Graphs (A), (B) have the domain of all real numbers and Graph (C) has the range of all real numbers.

Since all the parabolas are not the functions,

Therefore, Graph (C) is not a function. Graphs (A) and (B) are the functions.
