What is the y-intercept of the graph of the function f(x) = x2 + 3x + 5?
(0, –5)
(0, –3)
(0, 3)
(0, 5)

y-intercept of the function is (0, 5)

Step-by-step explanation:

Given function,

,

Or

,

Since, for y-intercept, x = 0,

Hence, the y-intercept of the given function is, (0, 5),

Last option is correct.

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
