Given the domain values {-3, 0, 3} what is the range for the equation f(x) = −5x + 2? Question options: {-3, 0, 3} {-6, 2, 6} {-
Fynjy0 [20]

The range is the set of all possible output, as you feed the function with all possible inputs. Since our inputs (domain) are -3, 0, 3, our outputs are

f(-3) = 15+2 = 17\\f(0)=0+2 = 2\\f(3) = -15+2 = -13

So, the range is

\{-13, 2, 17\}

Which of the following describes the end behavior of<br> f(x) = (1/2)^x
NARA [144]

Answer:

as x approaches infinity, f(x) approaches 0

as x approaches -infinity, f(x) approaches infinity

Step-by-step explanation:

we can observe that 1/2 < 1 and since it's being exponentiated, the f(x) gets smaller and smaller as x gets bigger.

For example, f(0) = 1, f(1) = 1/2, f(2) = 1/4

so, as x approaches an infinitely large number, f(x) gets closer and closer to zero.

this is the opposite as x approaches a negatively large number. following exponential rules, 1/2^(x) = 2^x for all x < 0. therefore as x approaches negative infinity, f(x) approaches infinity.

in this case, f(-1) = 2, f(2) = 4, f(3) = 8

Please Help!!<br> f(x) = square root of x plus 7 ; g(x) = 8x -11 <br> Find f(g(x))
Sonja [21]

I'm not sure if you mean ( \sqrt{x + 7} ) or ( \sqrt{x}  + 7 ) I solved it both ways .

f(x) =  \sqrt{x + 7}  \\  \\ f( \: g(x) \: ) =  \sqrt{(8x - 11)+ 7}  \\  =  \sqrt{8x - 11 + 7}  \\   =  \sqrt{8x - 4}  \\  = 2 \sqrt{2x - 1}

____o_____o______

f(x) =  \sqrt{x}  + 7 \\  \\ f( \: g(x) \: ) =  \sqrt{(8x - 11)}  + 7 \\  =  \sqrt{8x - 11}   + 7\\

I hope I helped you^_^

Circle A contains all positive odd numbers; circle B contains all factors of 33, and circle C contains all prime numbers. How ma
jarptica [38.1K]
3 and 11 are the only two because 33 only has four factors: 1,3,11,33.
1 - in some cases people say this is prime, but it is now widely considered to not be a prime number
3 - prime
11- prime
33 - not prime, divisible by 3 and 11
