Answer:

x^2 + 11x + 18.

Step-by-step explanation:

The length = x + 9 and the width = x + 2.

So the area

= length * width

= (x + 9)(x + 2)

= x(x + 2) + 9(x + 2)

= x^2 + 2x + 9x + 18

= x^2 + 11x + 18.

Let f(x)=4x+9. Write a function g whose graph is a reflection in the y-axis of the graph of f. g(x)= ?

frez [133]

Answer:

$g(x)=-4x+9$

Step-by-step explanation:

So we know that:

$f(x)=4x+9$

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

$g(x)=f(-x)=4(-x)+9$

Simplify:

$g(x)=-4x+9$

And that's our answer :)
