Help pl this is k12! Which function is equivalent tof(x)=4x2+12x+9?

Question 6 options:

(4x+3)(x+3)

(2x+3)2

(2x−3)2

(4x−3)(x−3)

Step-by-step explanation:

Factor the equation (I got 36 because I multiplied 4x9)

You need to find two numbers that multiple to equal 36 but add to equal 12

6 x 6 = 36

6 + 6 = 12

I used to box method to factor it further into (2x+3)^2

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
