Answer:

x^2+9x+8

Step-by-step explanation:

Expand the following:

(x + 1) (x + 8)

(x + 1) (x + 8) = (x) (x) + (x) (8) + (1) (x) + (1) (8):

x x + 8 x + x + 8

x x = x^2:

x^2 + 8 x + x + 8

Grouping like terms, x^2 + 8 x + x + 8 = x^2 + (8 x + x) + 8:

x^2 + (8 x + x) + 8

8 x + x = 9 x:

Answer: |

| x^2 + 9 x + 8

50 POINTS!!!!! HELPFor the exponential function f(x)=a^x,a>0,a≠1 what is the domain? what is the range?

White raven [17]

I have included a graph to help you see what the domain and range would be
There are no minus y values.
0<y< infinity y is included in the reals.
The domain is
- infinity < x < infinity.

I don't want to say that either x or y can equal - or + infinity. Some teachers allow it. You have to ask your instructor what they will accept.

The blue line is y = 4^x
The red line is y = 2^x
