Answer:
=
* 2 +
Step-by-step explanation:
lets start with what we know.
the recipe calls for 2 cups of yogurt. and Paolo doubles the recipe. so multiply the recipe for yogurt by 2
2 * 2 = 5 cups of yogurt.
the total of yogurt and oats is and we know how much yogurt we have so we subtract that from the total of both.
- 5 =
the oats after doubling were cups so u divide it by 2
/ 2 =
before doubling
Answer:
<h2>SEE BELOW</h2>Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>vertex:(h,k)
therefore
vertex:(-1,4)
axis of symmetry:x=h
therefore
axis of symmetry:x=-1
vertex form of quadratic equation:
therefore
it's to notice that we don't know what a is
therefore we have to figure it out
the graph crosses y-asix at (0,3) coordinates
so,
3=a(0+1)²+4
simplify parentheses:
simplify exponent:
therefore
our vertex form of quadratic equation is
let's simplify it to standard form
simplify square:
simplify parentheses:
simplify addition:
therefore our answer is D)y=-x²-2x+3
the domain of the function
and the range of the function is
zeroes of the function:
factor out x and -1 respectively:
group:
therefore
