Answer:
the answer is 36.4
Step-by-step explanation:
you have to multiply it by 4 so it it will look like this 9.1*4=36.4
1) first step
you must do( a+b) ^2 = a^2+2ab+b^2
then
2)second step
y = -3(x+1)^2 +4 = -3( x^2+2x+1) +4⇒ y = -3x^2-6x-3 +4, y = 3x^2-6x+1
now the graph of this function is
Answer:
