What is the real numbers for a, radical a squared

= a

Step-by-step explanation:

We have to evaluate the expression, 'Radical a squared'.

Now, radical means square root.

So, our expression becomes, 'Square root of 'a' square'.

That is, the expression is .

We know that, the square root of some squared value is the value itself.

So, = a

Hence, the real number for 'radical a squared' i.e. is 'a'.

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
