Let's examine the given function first:
f(x) = x^2 + 1 is the same as f(x) = 1(x-0)^2 + 1.
The vertex of the graph of this function is at (0, 1).
Let x=0 to find the y-intercept: f(0)=0^2+1 = 1; y-int. is at (0,1) (which happens to be the vertex also)
Comparing f(x) = x^2 + 1 to y = x^2, we see that the only difference is that f(x) has a vertical offset of 1. So: Graph y=x^2. Then translate the whole graph UP by 1 unit. That's it. Note (again) that the vertex will be at (0,1), and (0,1) is also the y-intercept.
Answer:
c. both
Step-by-step explanation:
Answer:
9 × 5= 45 .Frankie has 9 nickles.
Step-by-step explanation:
Because 5 divided by 45 equals to 9.
Y = 108/2 = 54
in case if you need to find x
x = 40/2 = 20
answer
y = 54
x = 20
It will cost $360 to enclose a square garden.
We need to find the perimeter of the square to know the number of meter needed and multiply it to the unit cost of the fence to get the total cost.
Given:
fence = 7.50 per meter
Area of a square = 144 m²
Area of a square = s²
s = √144m²
s = 12m
Perimeter of a square = 12m x 4 sides = 48 meters.
48 meters x $7.50 = $360
