Which of the following is true with respect to the following functions:
Mkey [24]

The option that is true with regard to the following functions is Option B. "The domain g(x) and h(x) include all real number while the domain of i(x) and h(x) are restricted"

<h3>What is the explanation for the above?</h3>

  • Lets examine f(x) = 3x + 14

Note that this function is indicative of a straight-line. See the attached graph for function 1. Note that it doesn't have any end points. That is, it is Asymptote.

  • Let us examine h(x) = 3ˣ + 1

This represents an exponential graph. Just like the function above it doesn't have any end point. It however has an asymptote:

y = 0

  • Let us look at F'(x) = Log₃ (x = 1).

This is indicative of logarithm graph. It doesn't have any end but has an asymptote x == 0

  • Let us take a look at g(x) = X⁴ + 3x² - 14

Notice that in the mid point there is an end point given as (0, -14). Thus, it is correct to state that the function in Option B is the only one that exhibits end behavior and as such is restricted.

Some of the students at Kahlo Middle School like to ride their bikes to and from school. They always ride unless it rains. Let d
algol [13]

Answer:

32d

Step-by-step explanation:

-The students ride their bikes to and from school every day. The distance is thus;

d_t=2d

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

Days=Days \ per \ week \times \ number \ of \ weeks\\\\=(5-1)\times 4\\\\=16\ days

Now, we multiply the distance per day by the total number of days:

Distance, D=2d\times 16\\\\=32d

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).
