1. Mathhelp346

like this? |dw:1334792959116:dw|

2. mrshappy0

I didn't see the ^2 sorry

3. Mathhelp346

is that right?

4. Mathhelp346

oh ok

5. mrshappy0

No, that is not correct

6. Mathhelp346

oh

7. Mathhelp346

but it's not supposed to be a parabola

8. mathhasproblems

well, to graph this, substitue different numbers for x, to graph it

9. Mathhelp346

10. mrshappy0

is it \[x^2+3 ?\]

11. vi3tbloodxx

\[2^{x} + 3\]

12. mrshappy0

oh

13. vi3tbloodxx

plug in x and solve. x = -2 x = -1 x = 0 x = 1 x = 2 you'll get a general idea of how it'll look

@Mathhelp346 the 3 is added to find the value of y. For example \[y = 2^{x} + 3\] x = 0 y = 2^0 + 3 = 1 + 3 = 4 y = 4 (0,4) would be one coordinate of the graph

16. Mathhelp346

oh ok

17. Mathhelp346

and then it would be x=2 and so on

18. vi3tbloodxx

wait is it \[2^{x} + 3 \] or \[2^{x+3}\]

19. Mathhelp346

2^x+3

20. vi3tbloodxx

then yea, just keep plugging in values for x, and solve for y

21. Mathhelp346

ok ty
