Hello :
f(x) = <span>a(x-k)²+k....... the point vertex is (h , k )
in this exercice : h = -3 and k = -1 s0 f(x) = a(x+3)²-1
find : a
but f(0)=8
a(0+3)² -1 = 8
9a-1=8
9a =9
a=1
f(x) =(x+3)²-1 =x²+6x+9-1
f(x) = x²+6x+8 .... (</span><span>the quadratic function in standard form )</span>
Answer:
13
Step-by-step explanation:
Use PEMDAS
2(3+2x5)÷2
first you would do the parenthesis
2 times 5 is 10
so now you have:
2(3+10)÷2You still have parenthesis so you would add 3+10 because that is inside the parenthesis
2(13)÷3
next you would do 2 times 13 which is 26:
so now you have 26÷2 which is 13
so the answer is 13
