F(x)=2x^2+8 and g(x)=x-3 what are their domains

Step-by-step explanation:

These equations are both continuous for all values of x so their is no restriction upon the domain. Both have a domain of (-oo, +oo)

The domain of f(x) and g(x) is the set of real numbers

Step-by-step explanation:

There are no restrictions on the values of x in either f or g.  So, the domains are the set of real numbers.

answer: no

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
