Answer:
- 8
Step-by-step explanation:
Evaluate f(1) and f(- 1) by substituting x = 1 and x = - 1 into f(x)
Given
f(x) = x² - 4x + 6, then
f(1) = 1² - 4(1) + 6 = 1 - 4 + 6 = 3
f(- 1) = (- 1)² - 4(- 1) + 6 = 1 + 4 + 6 = 11
Thus
f(1) - f(- 1) = 3 - 11 = - 8
Answer:
(A)29 cubic inch
Step-by-step explanation:
Diameter of the Cone =4 Inches
Height of the Cone =7 Inches
Volume of a Cone 
First, we determine the radius, r.
Radius=Diameter/2=4/2=2 Inches
Therefore:
Volume of one paper cone 
=29.32 cubic inch
=29 cubic inch (to the nearest cubic inch.)
Deductive. Since you're making the assumption from something that is mainly true
