1 answer:
LiRa [457]3 years ago
8 0

Answer:

x=3

Step-by-step explanation:

so in order to solve this question we are going to plug in u for 2^x

3((2^x)/2)=2^x+4

3u/2=u+4

3u=2u+8

u=8

we can put 2^x back into the equation in order to find x

2^x=8

2^x=2^3

x=3

Which Graph Represents A function ?<br><br> NEED ANSWER ASAP !!!!
ANEK [815]

Answer:

The very last one is a function

Step-by-step explanation:

The last one is a function because there are no y values that repeat. For example, If the points on one graph are like this; (1, 3) (2, 3); then it cannot be a function, the y values cannot repeat if it is a function.

To make things easier, just try to imagine vertical drawing lines through each point in every graph, if this imaginary vertical line passes more than one point in any graph, then that graph is not a function.

I hope this helps!! :D
