Step-by-step explanation:
a) f(4) = 7-2(4)
= -1
b) f(h) = 7-2(h)
= 7-2h
c) f(4) + f(h) = -1 +(7-2h)
= 6-2h
h = 3
d) f(3+h) = 7-2(3+h)
= 7-6-2h
= -1-2h
2h= -1
h = -1/2

The equations are:
Step-by-step explanation:
Let:
For Tina:
For Doug:
Solving for the price of both items:
We have:
--- (1)
--- (2)
Multiply (2) by 2
2 * ()
-------------------
--- (3)
Subtract (3) from (1)
----------------------
Solve for P
Substitute 1.25 for P in (2)

Solve for H
Vertex: (-2,1)
Maximum or Minimum: The graph has minimum point and gives minimum value because the minimum point gives the least y-value. That's why it is called minimum.
End of behavior:
When x approaches positive infinity, f(x) will approach positive infinity.
When x approaches negative infinity, f(x) will approach positive infinity as well.
Why no solution:
The graph doesn't intercept any x-axis. Therefore the graph doesn't have any solutions.
y-intercept: (0,5)
describe shape of the graph:
The graph decreases when x<0 and increases when x>0.
x<0 is concave up but decreasing
x>0 is concave up but increasing
Answer:
Explanation:
Volume of rectangular prism is same as volume of cuboid
Length = m units
Width = 6m units
Height = 5m units
Volume of rectangular prism = Length × Width × Height
= m × 6m × 5m
= 6m² × 5m
= 30 m³ unit³
