Answer:

b, a, e, h, f

Step-by-step explanation:

just test each variable

you can skip the ones that seem obviously wrong, like c, when you figure out the pattern.

b. |-5|=|-5|

g. |-3|≠|6|

a. |3|=|3|

e. |6|=|6|

j. |2|≠|-3|

h. |6|=|-6|

f.|-3|=|-3|

The function h(x) = x2 + 14x + 41 represents a parabola. Part A: Rewrite the function in vertex form by completing the square. S

denpristay [2]

Given the function h(x)=x^2+14x+41, to solve by completing square we procced as follows;
x^2+14x+41=0
x^2+14x=-41
but;
c=(b/2)^2
and b=14
hence;
c=(14/2)^2=49
substituting the value of c in the expression we get:
x^2+14x+49=-41+49
x^2+14x+49=8
(x+7)^2=8
this can be written in vertex form;
h(x)=a(x-h)^2+k
where:
(h,k) is the vertex;
thus
(x+7)^2=8
h(x)=(x+7)^2-8
hence the vertex will be at the point:
(-7,-8)
