If we let f(x)=2x+2 and solving for f-1(x) when x=4
f-1(x)=2(4)+2=10-1=9
Hope this helps. Any questions please just ask. Thank you.
Answer:
-26x-32
Step-by-step explanation:
distribute:
<u>-8 x 7x = -56x -8 x 4 = -32 10 x 3x =30x</u>
<u>Simplify:</u>
<h2>
<u>-26 -32</u></h2>
Answer:
Your question was incomplete, as the values are not given.
I guess these are the values you are talking about.
Hair Type Brown Blond Black Red Totals
Wavy 20 5 15 3 43
Straight 80 15 65 12 172
Totals 100 20 80 15 215
Now w have to find out the probability of a child with red, straight hair.
Total no of children with straight hair are = 172
The children having straight red hair = 12
The probability of selected child = 12/172.
Now let's examine the statements:
A)The functions have the same range:FALSE the range changed from y ≥ 0 to y ≤ 0
B)The functions have the same domains. FALSE the doman changed from x ≥ 0 to x ≤ 0
C)The only value that is in the domains of both functions is 0. TRUE: the intersection of x ≥ 0 with x ≤ 0 is 0.
D)There are no values that are in the ranges of both functions. FALSE: 0 is in the ranges of both functions.
E)The domain of g(x) is all values greater than or equal to 0. FALSE: it was proved that the domain of g(x) is all values less than or equal to 0.
F)The range of g(x) is all values less than or equal to 0. TRUE: it was proved above.
