nikklg [1K]

Answer:

Assuming the numerator was 1.

$(6\sqrt{7}+1)/251$

Step-by-step explanation:

Assuming the numerator was 1.

$1/(6\sqrt{7} -1)\\ (6\sqrt{7}+1)/((6\sqrt{7} - 1)(6\sqrt{7} + 1))\\ (6\sqrt{7}+1)/((6\sqrt{7})^2 + 6\sqrt{7} - 7\sqrt{7} - 1)\\(6\sqrt{7}+1)/((6\sqrt{7})^2 - 1)\\(6\sqrt{7}+1)/((36*7 - 1)\\(6\sqrt{7}+1)/251$

Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry for the function below.

telo118 [61]

<span>g(x) = x^2 + 4x + 3

y-intercept: let x=0. Then y=3. y-intercept is (0,3).

roots: set g(x) = 0 and solve for x. x=-1 and x=-3.

-4
axis of symmetry: find x = -b / (2a), which here is x = ----- = -2
