Answer:
Step-by-step explanation:
The given quadratic function is f(x)=2(2x^2+4x)+3
Multiplying through to open the brackets,
f(x)=4x^2 + 8x +3
To find the zeros, we will equate
f(x) = 0
Therefore,
4x^2 + 8x +3 = 0
Finding two numbers such that when we multiply them, it gives us 12xx^2 and when we add them, it gives us 8x, we have 6x and 2x. Therefore,
4x^2 + 8x +3 = 0 is expressed as
4x^2 + 2x + 6x +3 = 0
2x(2x + 2) +3(2x + 3) = 0
(2x +2)(2x +3) =0
f(x) = 2x +2)(2x +3)

Answer:
many answers,
Step-by-step explanation:
she could make 9 mugs, (3/4 x 9 = 12)
she could make 1 small bowl, 1 small plate, 2 large bowls and 2 mugs. (2.5 + 1.5 = 4, 3.25 x2 = 6.5 .75 x 2 = 1.5; 4+ 6.5= 10.5 10.5 + 1.5 = 12) etc
Answer:
Step-by-step explanation:
The inverse of can be calculated by swapping x and y and solving for y:
which corresponds to the third choice.
8/0.61=13.114… then round if needed
