F(x) = 2x2 + 12x + 1 Determine the vertex

Mathematics
1 answer:
Gnom [1K]3 years ago
5 0

Answer:

Step-by-step explanation:

The vertex would be the highest/lowest point so lets factor this first

when we factor we get

2(x^2+6x+8)

2(x+4) (x+2)

Using zero product property we find the 2 x values and x intercepts are

-4 and -2

the middle point of these points is -3

Substitute -3 for x and solve

2(-3+4) (-3+2)

2 * 1 *  -1

2*-1

-2

(-3,-2) is the vertex

The square with side length 2 cm is dilated by a scale factor of 7/3 is the dilated image larger or smaller than the original im
qwelly [4]
Length of square side= 2 cm
Dilation factor= 7/3
Simplify 7/3= 2.33
Apply the dilation factor:
Length of side= 2.33 x 2 = 4.67 cm
As the length of the side of the square is increased in length, which means the dilated image is larger than the original image.

Answer: Larger than then original.

A line that is not parallel nor perpendicular to y=2/4x+1
DENIUS [597]

Answer:

y=2x+1

Step-by-step explanation:

Parallel = gradients are the same

Example: y=2/4x+5

Perpendicular = gradients are the inverse of each other

Example: y= -4/2x+1

Any equation would be correct unless the gradient is 2/4 or -4/2
