Consider the first five terms of the following sequence. 3, 12, 48, 192, 768, ...

If the sequence defines a function, what is a reasonable domain and range of the
function?

a) Domain: (1, 2, 3, 4, 5, ...); Range: 3, 12, 48, 192, 768, ...}

b) Domain: {1, 2, 3, 4, 5, ...);
Range: all real numbers

c) Domain: all real numbers; Range: {3, 12, 48, 192, 768, ...)

d) Domain: all real numbers; Range: all real numbers

Step-by-step explanation:

It might be B

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
