Given g(x) = –2x + 1, find g(-1).

g(-1) =3

Step-by-step explanation:

g(x) = –2x + 1,

Let x = -1

g(-1) = –2 *-1 + 1

        = 2 +1

         = 3

3

Step-by-step explanation:

We just have to plug in -1 for x which gives us -2 * (-1) + 1 = 2 + 1 = 3.

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
