What is the domain of the function graphed below? Ox < 7
Ox < 7
O -2 < x < 3
O all real numbers

Step-by-step explanation:

At x=7, the graph ends with an open circle which mean less than so the domain is x < 7; the first choice.

Step-by-step explanation:

no end point for the function on left n a circle (not a dot which has different meaning) on right at x=7

so domain is x<7

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
