helpppp pllzzzz
which of the following quadratic function has a maxim a, f(x)(x+9)^2-9 b,f(X)=3/7(x-7)^2+9 c,f(x)=7/3(x+8)^2+9
Do you ever sleep?
lol yh i jst wake up nw hbu? men i trying to pass math class i ve really bad grd
Are you interested in LEARNING mathematics?
im but some hw i dont get it
can u help me with my question?
By the way, you say "I am", not "I'm"
Don't you have a graphing calculator?
no
Well, I highly recommend getting one
i will bt i dont know how to use it tho
You can learn how to use it.
okay i will
I graphed all three and they all have minimums
So please double check what you have posted
a, f(x)=-(x+9)^2-9 b,f(X)=3/7(x-7)^2+9 a, f(x)(x+9)^2-9 b,f(X)=3/7(x-7)^2+9 c,f(x)=7/3(x+8)^2+9 d,f(x)=7/3(x+8)^2+9
I think you mean that these are the answer choices: a, f(x)=-(x+9)^2-9 b,f(X)=3/7(x-7)^2+9 c,f(x)=7/3(x+8)^2+9 d,f(x)=7/3(x+8)^2+9 If so, the only option that will give a maximum is the one with a negative in front
yes, thanks
can u plz show me how u did it if u dont mind
I graphed it on my graphing calc, however, even without graphing, I know that if the leading coefficient of a quadratic is negative, then it will produce a maximum vertex.
So basically, even without graphing I would still be able to figure it out.
can u show me hw?
I'll try: y = ax^2 + bx + c produces: |dw:1351763668056:dw| y = -(ax^2 + bx + c) produces: |dw:1351763745072:dw|
