Question

The graph of the function f(x) = (x + 2)(x + 6) is shownbelow.6+4+What is true about the domain and range of the function?The domain is all real numbers, and the range is allreal numbers greater than or equal to 4.The domain is all real numbers greater than or equalto4, and the range is all real numbers.The domain is all real numbers such that -6 585-2,and the range is all real numbers greater than or equato-4.The domain is all real numbers greater than or equalto4, and the range is all real numbers such that -6 5xS-2.2+++++-446xN12-2+-4-6

Answer 1

hi

The domain is all the points of the blue line in the x-axis

The range is all the points of the blue line in the y-axis

That's why:

Domain = all real numbers

Range = [-4, infinity] because the line starts in -4 in the y-axis
