Answer:

(fºg)(x) = x -2

Step-by-step explanation:

f(x) = x + 2

g(x) = x - 4

(fºg)(x) = ( x - 4) + 2

(fºg)(x) = x -2

Find the solutions to x² = 12.

Novosadov [1.4K]

Answer:

$x = \pm 2\sqrt3$

Step-by-step explanation:

Hello!

Let's use the square root property to solve this question

Solve:

$x^2 = 12$
$\sqrt{x^2} = \sqrt{12}$
$x = \pm\sqrt{12}$
$x = \pm \sqrt{4 * 3}$
$x = \pm 2\sqrt3$

The answer is option A: x = ±2√3

Given: a quadratic function with vertex (2,3) opening upward .

Find: the given statement is true or false.

Explanation: if parabola has a vertex at (2,3) and opens upward, it has one real solution., (2,3) will be a lowest point. The vertex will be at lowest point, it will be minimum.

that means graph has no one real solution. hence it will never going to intersect. so this statement is false.

Final answer: the given statement is FALSE.

If `f(x)=x^2-81` and `g(x)=(x-9)^(-1)(x+9)`, find `g(x)xxf(x)`.

marshall27 [118]

Answer:

$g ( x ) * f ( x ) = ( x + 9 ) ^ 2$

Step-by-step explanation:

We are given the following two functions and we are to find $g(x) * f(x)$ :

$f(x)=x2-81$

$g(x)=(x - 9)^{-1} ( x + 9)$

$g(x)*f(x)=x^{-81} * \frac{x+9}{x-9}$

$g ( x ) * f ( x ) =\frac{(x+9)(x-9)(x+9)}{x-9}$

$g ( x ) * f ( x ) = ( x + 9 ) ( x + 9 )$

$g ( x ) * f ( x ) =( x + 9 ) ^ 2$

Parallel never cross
perpendicular is a 90 degree angle
its neither if its not 90 degree or never crossing
