Y=-2x^2+2x-4. Should be correct
Answer:
Algebrically the result can be written as -

Step-by-step explanation:
Let the number be 'x'.
- When multiplied by 3 , algebrically it is written as "3x".
- When 4 is added to 3x , algebrically it is written as "3x + 4".
- When (3x + 4) is squared completely , algebrically it is written as -

Ok, so we see in
y=a(x-h)^2+k
vertex is (h,k)
vertex is highest or lowest point
on one side, it goes up and other side it goes down
if a is positive, then it goes down then up
if a is negative, it goes up then down
we see
f(x)=2(x+3)^2+2
2 is positive
goes down then up
vertex is (-3,2)
so decreases from -infinity to -3 or ininterval
(-infinity,-3)
answer is first option
We know, Surface area of a Cube = 6a²
Here, Edge length(a) = 1.5
Substitute the value,
s = 6(1.5)²
s = 6 * 2.25
s = 13.5
In short, Your Answer would be Option D
