Answer:
(a) 3 - 2x - 2x² (b) -21
Step-by-step explanation:
given, y +2x² = 3 -2x
make y the subject:
y = 3 - 2x - 2x²
if y = f(x)
then
f(x) = 3 - 2x - 2x²
(b)<u> to find f(3) we need to replace x with 3:</u>
<u />
3 - 2(3) - 2*(3)²
-21

It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .
The formula of volume of cone is
To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is
And that's the required volume of the cone .
Answer: The y intercepts would be: ( 0 , -2 ).
The x intercepts would be: ( 1 , 0 ).
Step-by-step explanation:
Angles in a triangle adds up to 180
