Step-by-step explanation:
The vertex form of a parabola is
... (1)
where, a is a constant (h,k) is vertex.
The given function is
The vertex of the function is (0,0) and it goes through (-2, 4) and (2, 4).
It is given that the vertex of function g(x) is at (5,2).
Substitute h=5 and k=2 in equation.
g(x) is passes through (3, 6).
.... (2)
Divide both sides by 4.
Substitute a=1 in equation (2).
The function g(x) is .
Therefor, the correct option is 4.
Answer:
B
Step-by-step explanation:
Converting it to z, we can use the formula of z-score:
z-score =
Where
x is the value we are checking for (here, x = 79)
is the mean, which is 85
is the standard deviation, which is 4 now
