If f(c) = 2x^2. +4 find f(3)

22

Step-by-step explanation:

SImply replace x with 3.

f(3)=2x^2 + 4

    =2(3)^2 + 4, (RE: PEMDAS, so first solve the exponent: 3^2)

    =2(9) + 4      (Multiply 9 and 2)

    =18 + 4         (Add)

    =22

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
