The vertex is (3,5).

There is no x intercept. Because

$0=(x-3)^2+5$ has no real solutions.

The y intercept is 14. Because:

$y=(0-3)^2+5=14$

Let f(x) = 7x² + 19x + 21 and g(x) = 4x² + 4x + 3 . Identify the solution(s) of f(x) = g(x).

tresset_1 [31]

Answer:

-3 and -2

Step-by-step explanation:

7x² + 19x + 21 = 4x² + 4x + 3

combine like terms:

3x² + 15x + 18 = 0

3(x² + 5x + 6) = 0

(x + 3)(x + 2) = 0

x = -3

x = -2
