The following graph of f(x) = x^2 has been shifted into the form f(x) = (x − h)^2 + k:

Answer:
h = 5 or h = 3
Step-by-step explanation:
f(x)=(x-h)^2 is a parabola
The vertex of a parabola is its lowest or highest point.
So (4,1) is a point on f(x)
substituting into the new equation, 1 = (4-h)^2
4-h = 1 or 4-h = -1
h = 5 or h = 3
Answer:
k = 1
Step-by-step explanation:
f(x) = x^2 has vertex at (0,0)
new form f(x)=(x-h)^2+k w vertex @ (4,1)
at vertex, f(x) is at minimum: because (x-h)^2<u> ></u> 0, the minimum = k
k = 1

Answer:
C(n)=1.25n
Where n= number of cans
Step-by-step explanation:
C=cost
n=number of cans
Quantity Total cost
1 $1.25
2 $2.50
3 $3.75
4 $5.00
Total cost, c(n) =1.25n
Check
Total cost when n=4
Total cost c(4)=1.25×4
Total cost c(4)=5.00
No because (-7, 3) is like (x, y)
Answer:
25 Feet
Step-by-step explanation:
If the man is 5 feet and he cast a shadow of 4 feet that means that there is a 1 foot difference. So, subtract the shadow hight by 1.
use pythagoras:
c^2 = (27)^2 - (13)^2
c^2 = 560
c = 23.6643....cm
