Answer:
we have
using a graph tool
see the attached figure
the domain of the function is all real numbers------> the interval is (-∞,∞)
the range of the function is --------------------------------> the interval (-∞,9]
therefore
the answer is
The range of the function is all real numbers less than or equal to 9
Step-by-step explanation:
The answer is B.
B is the answer because:
2(1)-8= -6
2(2)-8= -4
2(3)-8=-2
2(4)-8=0
Answer:
(6,-34)
Step-by-step explanation:
You can use the vertex formula to find the x of the vertex and then plugin the x value into the formula to find the y value.
Now plugin 6 into y=x²-12x+2
y=x²-12x+2
y=6²-12(6)+2
y=36-72+2
y=36-72+2
y = -34
Vertex = (6,-34)
A reasonable estimate is like 8 or 9 or maybe even 10
hope this helps
<h3>For 5 toppings, cost of tony and bob are same</h3>
<em><u>Solution:</u></em>
Let "x" be the number of toppings
Given that,
Tony's hamburgers shack sells hamburgers for $2 plus $0.40 for each topping
Therefore,
Cost = 2 + 0.40x ----- eqn 1
Bob's burgers sells hamburgers for $3 dollars plus 20 cents for each topping
20 cents = $ 0.2
Therefore,
cost = 3 + 0.2x -------- eqn 2
For both the cost to be same, eqn 1 is equal to eqn 2
2 + 0.40x = 3 + 0.2x
0.40x - 0.2x = 3 - 2
0.2x = 1
Divide both sides by 0.2
x = 5
Thus, for 5 toppings, cost of tony and bob are same
