Functions f, g, and h are shown on the graph. Which of these functions have a domain of all real numbers?
A. Functions f and g only
B. functions g and h only
C. Functions f only
D. Functions f, g, and h

Option (D)

Step-by-step explanation:

Domain of a function is defined by the x-values (input values) of the graph.

Similarly, Range is defined by the set of y-values (output values) of the graph of the function.

From the graph attached,

Domain of function 'f' : {x | x ∈ R}

Domain of function 'g' : {x | x ∈ R}

Domain of function 'h' : {x | x ∈ R}

Therefore, all the function graphed have domain of all real numbers.

Option (D) will be the answer.

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
