Answer:

All real numbers greater than or equal to -1

Step-by-step explanation:

f(x) = (x-4)(x-2) = x²-4x-2x+8

f(x) = x²-6x+8

f(x) = [(x)²-2(x)(3)+3²-3²]+8

f(x) = (x-3)²-9+8

f(x) = (x-3)²-1

The function has a least value of -1.

So, the range is also all real values greater than or equal to -1

Two cones have a radius of 2 cm. The height of one cone is 8 cm. The other cone is 1/4 of that height. Which of these statements

marta [7]

The wrong statement: The volume or the smaller cone cannot be determined because its height is unknown.

We already know that the larger cone has a height of 8 cm and that the smaller cone is just 1/4 of 8 cm.

8×1/4 = 2 cm.

You can still find its volume by using the formula 1/3πr^2.
