Solve this I need it solved

Answer:

option 3

Step-by-step explanation:

$Standard \ quadratic \ equation : ax^2 + bx +c$

Larger the value of '' a '' makes the parabola narrow.

A positive value of '' a '' which is close to 0 makes the parabola wide.

To find the widest graph , find the smallest a. (or a closest to zero)

option 1

$a_1 = \frac{1}{3}$

option 2

$a_2 = - \frac{4}{5}$

option 3

$a_3 = 0.3 = \frac{3}{10}$

option 4

$a_4 = -4$

Positive and negative value of ' a ' decides the direction the parabola opens.

But we have to find the widest parabola irrespective of the direction.

So we will find the smallest ' a '

$a_1 = 0.33\\a_2 = 0.80\\a_3 = 0.30\\a_4 = 4$

$a_3 \ is \ the \ smallest \ number \ or\ \\ the \ number \ closest \ to\ zero.\\\ so \ option \ 3 \ makes\ the\ widest \ parabola.$

g(x) = x3 + 6x2 + 12x + 8 Determine the function’s value when x = −1. g(−1) = −3 g(−1) = 0 g(−1) = 1 g(−1) = 27

yawa3891 [41]

The correct answer is that g(-1) = 1.

To do this problem, we have to plug in -1 for x and evaluate the expression.

g(-1) = x^3 + 6x^2 + 12x + 8

(-1)^3 + 6(-1)^2 + 12(-1) + 8

-1 + 6 -12 + 8

Use the Elimination method and solve 4x+6y=3 and -10x-15y=-4

aleksandrvk [35]

Answer:

No Solutions

Step-by-step explanation:

Multiply the first equation by 5,and multiply the second equation by 2 to get a least common multiple for the x's.

5(4x+6y=3)

2(−10x−15y=−4)

It becomes:
