parent function question

OpenStudy (watermelon14):

@jim_thompson5910 plz help

@satellite73 plz help me

OpenStudy (watermelon14):

i need help on the general function part

jimthompson5910 (jim_thompson5910):

I'm not sure what they're looking for, but it may be something like y = ax^3 + bx^2 + cx + d basically a,b,c,d are fixed numbers ------------------------------------------------------- example: a = 2, b = 7, c = 10, d = -2 so, y = ax^3 + bx^2 + cx + d becomes y = 2x^3 + 7x^2 + 10x - 2

OpenStudy (watermelon14):

wait but i was thinking could the general equation be the same as the parent function ?

OpenStudy (watermelon14):

parent equation*

jimthompson5910 (jim_thompson5910):

not necessarily

jimthompson5910 (jim_thompson5910):

for example y = x^2 is a parent function for a quadratic in general, the quadratic equation is y = ax^2 + bx + c

jimthompson5910 (jim_thompson5910):

a specific quadratic equation would be y = 3x^2 - 10x + 14 where a = 3, b = -10, c = 14

OpenStudy (watermelon14):

thanks, but i still don't understand wat to put of the general equation

jimthompson5910 (jim_thompson5910):

y = ax^3 + bx^2 + cx + d is as general as it is going to get from there, you would replace a,b,c,d with actual numbers to go from general to specific

OpenStudy (watermelon14):

the #'s are the plots on the graph right ?

jimthompson5910 (jim_thompson5910):

sorta, they dictate the shape and the position of the graph in a way

jimthompson5910 (jim_thompson5910):

for example, the 'd' in y = ax^3 + bx^2 + cx + d, tells you how to shift the parent function y = x^3 up and down

jimthompson5910 (jim_thompson5910):

since that is the y-intercept

OpenStudy (watermelon14):

ohhh i see thank you very much! :)
