The one is a vertical translation of the parent function to the left of one
making it -1.
Y = x² + 4x + 4.. Since the coefficient of x² =1, is positive, then this parabola opens upward & has a minimum.
Its axis of symmetry is = -b/a = -4/1 = 4 (so x=4)
1) When x=4, y= 4²+4(4)+4 => y=36 so the VERTEX has a minimum is at (4,36)
2)FOCUS.: To be able to calculate the focus, rewrite the equation in a standard form: y-k =a(x-h)² & y = x² + 4x + 4 could be written y=(x+2)², this means that k=0 & h=-2.
Now p being the distance between the VERTEX & the FOCUS, we apply the formula (x-2)² = 4P (y-k) , but k=0 & h=2 then (x-2)² = 4P(y-0) then P =1/4
3) DRECTRICE : y=k-P = 0-1/4 ==> y=-1/4 is the directrix

Answer:
y = $45 + x
y = $5 + 3x
Step-by-step explanation:
The computation of the multi-step equations be shown below:
Let us assume the number of visits be x
So the first equation would be
y = $45 + x
And, the second equation would be
y = $5 + 3x
These are the multi-step equations with variable on the both sides
2/3-1/4=5/12
You could make the denominators common by finding the GCF
The GCF of 4 and 3 is 12
This means that 8/12-3/12 which would give you 5/12.
