F(x) = -3x^2 + 6x. Find f(2).

inysia [295]

Answer:

f(2) = 0

Step-by-step explanation:

Evaluate the function at x = 2.

f(x) = -3x^2 + 6x

f(2) = -3(2^2) + 6 * 2

f(2) = -3(4) + 12

f(2) = 0

PLZZZZ HELP A. 178.3 B. 196.5 C. 250.8 D. 292.5 E. 297. 1

stepladder [879]

Answer:

E, 297.1

Step-by-step explanation:

First, find the area of the triangle using the formula a= (bh) / 2

Base x height would be 16 x 12, which is 192

192 / 2 is 96 sq meters

Then, find the area of the circle using the formula a= Pi (r^2)

If the diameter is 16, the radius would be 8 because you divide by 2

8^2 is 64, 64 times Pi is approximately 201.1

Finally, add the areas together, 96 + 201.1 is 297.1 or E

Write the equation of the parabola in vertex form. Vertex (1,2) point (2,-4)

lozanna [386]

Answer:

$f(x)=6(x-2)^2-4$

Step-by-step explanation:

The equation in vertex form is

$f(x)=a(x-2)^2 - 4$

Substituting in the coordinates (1,2) to find a,

$2=a(1-2)^2 - 4 \\ \\ 2=a-4 \\ \\ a=6 \\ \\ \therefore f(x)=6(x-2)^2-4$
