Answer:
11
Step-by-step explanation:
it has a vertex at (2,11)
.
f(2) = 11
how to find the vertex;
function equation is f(x) = ax^2 + bx + c
we can find x by :-b/2a, -8/-4 = 2
and by putting the x value we get the y
x= -b/2a
x= -8/2(-2)
x=-4/-2
x=2
f(2) = -2(2) +8(2)+ 3
f(2) = -8 +16 + 3
Maximum value is 11
f(x)=-4x+/4
let y=f(x)
y=-4x+4
interchange the role of x & y
x=-4y+4
x-4=-4y
(x-4)/-4=y
y=-(x-4)/4
f-¹(x)=-(x-4)/4
yeah you are right
We have the vertex (-4, -1), therefore we have:
25,26,27,28,29
