Answer:
True
Step-by-step explanation:
Its true since it passes the vertical line test. How does the vertical line test work? You put a vertical line through a point and if it has only one point on that specific line it is a function. Note:hope this helps
Answer: D
Explication: 8z>=16
z>=16/8
z>=2
Zed is bigger or equal to 2 meaning the line has to go to the positive infinity side and it’s equal to 2 so the circle has to be filled
For this case we must solve the following equation:
To solve we follow the steps below:
We square both sides of the equation squared:
We choose the positive value because we talk about $. 
Answer:
$6

Step-by-step explanation:
Given:
Answer:
(-2, -4)
Step-by-step explanation:
y = f(x) = ax²+bx +c
given the vertex is (3, -4)
=> the symetry axis: x = 3
x = -b/2a = 3
so, -b = 6a => b = -6a
the function f(x) = x²-6x + 5
g(x) = f(x+5)
g(x) = (x+5)²-6(x+5)+5
g(x) = x²+10x+25-6x-30+5
g(x) = x²+4x
=> a=1, b=4
find the vertex of the function g :
the symetry axis: x= -4/2(1) => x = -2
y = g(-2) = (-2)²+4(-2)= 4-8 = -4
so, the vertex is (-2, -4)
