Answer:

(1;1) and (0;4)

Step-by-step explanation:

1) if given f(x)=3x²-6x+4 (where a=3; b=-6 and c=4), then

x_0=\frac{-b}{2a}; \ = > \ x_0=1;

y_0=3*1-6*1+4=1;

it means, the vertex has coordinates (1;1).

2) if according to the condition x=0, then

f(0)=0-0+4=4;

it means the Y-intercept is 4.

BRAINLIESTTT ASAP! PLEASE HELP ME :)

Answer:

x = 52, y = 137 degrees.

Step-by-step explanation:

x = 180 - 90 - 38

x =  52 degrees   (as there is 180 degrees in a triangle).

As they are the same side inner angles between 2 parallel lines:

x + (y - 9) = 180

52 + y - 9 = 180

y = 180 - 52 + 9

y =  137 degrees.
