What is the reflection image of U across the y-axis?
2 answers:
Answer:
B.
Step-by-step explanation:
We have been coordinates of some points on coordinate plane. We are asked to find the reflection image of U across the y-axis.
We know that after reflecting a point across y-axis, the y-coordinate of point remains same, while x-coordinate changes to its opposite sign.
We can see that coordinates of point U are . After the reflection across y-axis the y-coordinate will remain same that is
, while x-coordinate will be opposite of
that is
Therefore, the coordinates of point U after reflection across y-axis would be and option B is the correct choice.

Answer:
Step-by-step explanation:
hello :
the vertex -form of quadratic function f(x) is : f(x) = a(x+b)²+c
the vertex : (- b , c )
means : (-2,-3) so : -b = -2 and c = - 3 so : b =2 and c = -3
f(x) = a(x+2)²-3
calculate : a
the graph passes through the point (2, 13) : f(2)=13
means : a(2+2)²-3 = 13
16a - = 13
16a = 16 so : a = 1
f(x) is represented by the equation f(x) = (x+2)²-3
The graph of f(x) color red and g(x) blue
is the y-intercept when g(x) greater g(x) than f(x) is when x=0 so : y = 6
