1. Which of the following is a quadratic function?
(1) y=3x – 2
(2) y=x²+2x²–1
(3) y=x² - 4
(4) y=6(2)*

2 and 3

Step-by-step explanation:

Anything that is to the power of 2 is quadratic

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

what level of math? also i don't need to be paid if i can you.
