Arrange the functions in descending order, starting with the function that eventually has the greatest value and ending with the function that eventually has the least value. tiles 4x + 9, 9x + 1 ,x2 + 3 ,4x ,9x ,x2

Answer with explanation:

→Area of Rectangle = Length × Breadth

→Area of Square = (Length of side)²

⇒4 x= Area of Rectangle having length of one side= 4 units and length of other side equal to x units

⇒ 9 x=Area of Rectangle having length of one side= 9 units and length of other side equal to x units.

⇒x²=Area of Square having length of each side= x units

It must be Kept in mind that, side length can't be Negative.

So, if x is a Positive real number >0, then almost in all the cases

⇒x²< x²+3< 4 x < 4 x+9 < 9 x < 9 x+1

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
