Question

x^2+3 what is the domain, range, interval of increase and decrease,maximum and minimum

Answer 1

domain=all real numbers
range=y greater or equal to 3

Answer 2

it has a min pt

Answer 3

minimum = f'(0)=0

Answer 4

so the domain would be \[-\infty,\infty\]

Answer 5

f'(x)=0 i mean

Answer 6

exactly

Answer 7

i dont get the minimum or maximum

Answer 8

are you in calculus?

Answer 9

no accelerated math 2

Answer 10

yes but if she's not in calc, then she doesn't know the derivative lol

Answer 11

\[f(x)=x^2+3=(x-0)^2+3\]
vertex is (0,3)
the graph is concave up
so the range is from 3 to infinity
[3,inf)

Answer 12

the inteval of increase is x>0 or x<0

Answer 13

it can also be said that the range is grater than or equal to 3

Answer 14

what is the maximum and what is the interval of decrease

Answer 15

no max
interval of decrease (-inf,3)
