Answer:
The vertex is (0,0)
Step-by-step explanation:
To find the x coordinate of the vertex
x = -b/2a where ax^2 +bx +c
a=1 b=0 c=0
x = -0/2(1) = 0
The y value is found by substituting into the equation
y = (0)^2 =0
The vertex is (0,0)
Answer:
Domain: x>=1
Step-by-step explanation:
what values of x make it work (square roots must be greater than or equal to zero)
sqrt (5x-5) >=0
square each side
5x-5 >=0
add 5 to each side
5x>=5
divide by 5 on each side
5x/5 >=5/5
x >=1

This line crosses the point (4,5)so we can make an equation to find the slope:
