Answer:
Step-by-step explanation:
abs ( -2(5-(-1)) / 3 )
= abs ( -2(5+1) / 3 )
= abs ( -2(6) /3)
= abs (-12 /3)
= 4
(3(-1) -- 1) /2
= (-3 -1) /2
= -4 / 2
= -2
since 4 is greater than - 2 this is inequality is true
Answer:
The formula for this quadratic function is x*2 +6x+13
Step-by-step explanation:
If we have the vertex and one point of a parabola it is possible to find the quadratic function by the use of this
y= a (x-h)*2 + K
Quadratic function looks like this
y= ax*2 + bx + c
So let's find the a
y= a (x-h)*2 + K where
y is 13, x is 0, h is -3 and K is 4
13= a (0-(-3))*2 +4
13=9a +4
9=9a
9/9=a
1=a
The quadratic function will be
y= 1(x+3)*2 + 4
Let's get the classic form
(x+3)*2 = (x+3)(x+3)
(x*2+3x+3x+9)
x*2 +6x+13
f(0) = 13
