OpenStudy (tori1423):
f(10) = f(x)
jhonyy9 (jhonyy9):
do you see the line where x = 10 ?
jhonyy9 (jhonyy9):
so on the other part how many is the value of y ? so this will be the value of f(10) bc.
y mean f(x)
OpenStudy (jojo12g):
i think C
jhonyy9 (jhonyy9):

OpenStudy (jojo12g):
i think C or D
jhonyy9 (jhonyy9):
why c or d you need to be sure bc. just one line has there x value of 10 so on the other part of this 10 how many is the y value ?
OpenStudy (jojo12g):
so then B
jhonyy9 (jhonyy9):
not B. bc. this mean 10 value for y and you need getting the 10 value where is for x
