Question

Help me with 2 problems?(attach, and medal)

Answer 1

@BlackLabel i think it is c

Answer 2

hmmm the first one or the second one?
Which question?

Answer 3

the first

Answer 4

I was thinking that its B
Ok for starters we know the Domain must be 0 or greater because we cant squareroot a negative number

Answer 5

right

Answer 6

ok now the square root of a postive number is always postive
So lets take our smallest number which is 0
cubed root(0)=0
and 0+2=2
So our range is anything greater than 2
Ok I am horrible at explaining this

Answer 7

i understand the range, just the domain i wanted to check

Answer 8

The answer is B then

Answer 9

ok

Answer 10

so the second may be b too but its -4

Answer 11

Its C
ok the domain must be greater than 0
Now the squareroot will always be positive so a negative * positive will always be negative
The only time it wont is when the sqrt =0 and in that case our f(x) will equal 0
So the range is f(x)< or equal to 0

Answer 12

so - 4 does not matter?

Answer 13

the -4 makes it always negative

Answer 14

so the graph will always be negative except by the origin
The answer is C

Answer 15

oh ok, i see what you mean

Answer 16

thank you
