I'm having a bit of trouble finding out how to find the Domain of this function. Help please!

BabaBlast [244]

In general, the domain is the set of all x-values for the graph.

The issue here is that this isn't the graph of a function. A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.

So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.

The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?

What's m2-5m-14=0 solved using the quadratic formula?

Mashutka [201]

The answers are x=7 or x=-2

$x=-b$ + $\sqrt{b ^{2} -4ac}$ /2
x=5 + $\sqrt{(-5) ^){2}-4(1)(-14 }$ /2
x=5 + $\sqrt{25+56}$ /2
x=5 + $\sqrt{81}$ /2
x=5 + $\sqrt{81}$ /2.....x=7
or
x=5 - $\sqrt{81}$ /2....x=-2

What is the value of 2 thirds + 3 fourths

inn [45]

Step-by-step explanation:

⅔ + ¾

→ make the denominator equal of both the fraction

= 2/3 × 4/4 = 8/12

= 3/4 × 3/3 = 9/12

hence,

8/12 + 9/12

= 8 + 9/12 = 17/12

$\frac{17}{12} or \: 1 \frac{5}{12}$

hope this answer helps you dear...take care
