As it has a maximum value the coefficient of x^2 will be negative
The vertex will be at (-8,2) so in vertex form it is
y = a(x + 8)^2 + 2
and as it passes through (-7,-1) we have:
-1 = a(-7+8)^2 + 2
-1 = a + 2 so a = -3
answer is y = -3(x + 8)^2 + 2
in standard form this is y = -3x^2 -48x - 190

Answer:
abdef (those are the answers)
Step-by-step explanation:
Hello :
the nth term is : An =A1 × r^(n-1)
A1 = 1 r = 2.3 n = 5
A5 =1 × (2.3)^(5-1)=27.9841
= (x^18y^24)/(x^2y^2)
Simplified = x^16y^22
The last answer is correct (x^16y^22)
