WILL MARK BRAINLIEST Describe the change in the graph of the parabola f(x) when it transforms into g(x) = −3f(x). The parabola g(x) will open in the opposite direction of f(x), and the parabola will be narrower than f(x). The parabola g(x) will open in the same direction of f(x), and the parabola will be narrower than f(x). The parabola g(x) will open in the opposite direction of f(x), and the parabola will be wider than f(x). The parabola g(x) will open in the same direction of f(x), and the parabola will be wider than f(x).

a) opposite direction and narrower

Step-by-step explanation:

g(x) = -3 f(x)

A reflection means it opens in the opposite direction

If f(x) is U-shaped, then g(x) is ∩-shaped.

A vertical stretch means g(x) will be narrower than f(x).

If f(x) has a width of U, then g(x) will have a width of ∪.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
