How do you know if a function is quadratic??
Anestetic [448]

Answer:

Usually it's in standard form: ax²+bx+c

or vertex form: y=a(x-h)²+k

If you put the graph into a graphing calculator it's going to look like a hill/depression.

Step-by-step explanation:

Standard form ex: 3x²+2x+1

Vertex form ex: y=4(x-1)²-2

E5 In (x + 1)<br> Simplify
pentagon [3]

Answer:

e^ (5 ln (x + 1))   = (x + 1)^5

Step-by-step explanation:

e5 In (x + 1)  or did you mean   e^ (5 ln (x + 1))

because then this would simplify a lot

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5)

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5) = (x + 1)^5

or did you mean  (e^5) ( ln (x + 1))  =  ln [(x+1)^(e^5)]

But I think you meant:

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5) = (x + 1)^5
