+360 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!!!!
+129852 Here's the first one, PF : https://www.desmos.com/calculator/ysfv3ogzwy
The x values are - 2 and -1
+129852 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 ]
+360 Thank you so much! The explanations refreshed my memory for the other ones as well!!
+37146 (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
