The answer should be C, if my math is correct!
Hope I could help :)
Domain x€R
range y€[1,+ the eight that goes side ways}
minimum (0,1)
vertical intercept (0,1)
answer : y=x2+1
The 1st one
Well it's the same as normal exponents so you multiply 2/3 x 2/3 x 2/3 x 2/3 x 2/3
Please write that as 4.321 × 10^(−4). The " ^ " indicates exponentiation and the parentheses help make clear that your exponent here is a negative one.
Rewrite 4.321 × 10^(−4) by moving the decimal point 4 places to the left:
0.0004321
7.2>0.9(n+8.6)
multiply 0.9 by all in parentheses
7.2> (0.9*n) + (0.9*8.6)
7.2> 0.9n + 7.74
subtract 7.74 from both sides
-0.54> 0.9n
divide both sides by 0.9
-0.6> n
ANSWER: -0.6> n
Hope this helps! :)
