REally need help asap.

1.

Graph the functions on the same coordinate plane.

f(x)=x2+6x+8

g(x)=−x2+4

What are the solutions to the equation f(x)=g(x)f(x)=g(x)?

Select each correct answer.

−2

−1

0

2

3

2.

What is the expression in radical form?

(8)5/2 Must be simplest form

3.

Thanks so much!!!!

Here's the first one, PF : https://www.desmos.com/calculator/ysfv3ogzwy

The x values are - 2 and -1

Don't understand the second one

Last one

(8x^7y^4)^(2/3) =

8^(2/3) *(x^7)^(2/3) * (y^4)^(2/3)

[8^(1/3)[^2 * [x^14/3] * [y^8/3]

2^2 * x^4 * x^(2/3) * y^2 * y^(2/3)

4x^4y^2 ∛ [ x^2 y^2 ]

(8)^{5/2}= ( 2*2*2)^5/2 = (4*2)^5/2 = 2^5 * 2^5/2 = 32 (2*2*2*2*2)^1/2 = 32 * 4 sqrt2 = 128 sqrt 2
