I have two Profit functions which i have to show a relation on a graph in excel and i'm stuck. Thanks for any help

P=-10^-5 x^2 + 20x-7,000,000


P= -10^-5 x^2 + 30x-7,000,000

Here's the work if it helps

p(x)= 60-10-5 x
p-60/-10-5 =x

P=R-C
P= (60-10-5 ) (x)-(30x +7,000,000)
60x-10-5 x2 -30x-7,000,000
P= -10-5 x2 + 30x-7,000,000
P1=2 (-10-5 )X+30=0
X=1,500,000
P(x)=60x-(10-5 )(1,500,000)=
P= $45

Profit = (60-10-5 x)(x) –(40x+7,000,000)
P= -10-5 x2 +60x-40x-7,000,000
P= -10-5 x2 +20x-7,000,000
P1= 2(-10-5 )x+20
X= 1,000,000
p(-x)=60x-(-10-5 )(1,000,000)
p= $50
