The function classification of this graph and explanation for it

What is NOT a function and because it has two outputs for at least one input ( fails vertical line test) ?

1

Determine algebraically if the following function is Even, Odd, or Neither

f(x)= sqrt(x-5) +2

What is Neither?

f(-x) is invalid so Even and Odd test failt

Sketch a graph that satisfies the condition and name it

Various answers work, for example:


1

Find Domain and range:


R: yge-1  or [-1, infty)

D:[-2,infty)

1

What is Yes, it is a Function? And what are 

D:\{a_1, a_2, a_3,a_4\}, R: \{b_1, b_3, b_4\}, CD: \{b_1,b_2,b_3,b_4,b_5\}?

2

Determine algebraically if the following function is Even, Odd, or neither:

g(x) = {6x^3}/{7-x^4}

What is Odd?

g(x)={6x^3}/{7-x^4}

g(-x)= {6(-x)^3}/{7-(-x)^4}={-6x^3}/{7-x^4}= -{6x^3}/{7-x^4}

therefore g(x) = - g(-x)

The meaning of an even function and the meaning of an odd function. Also provide the tests we do for them

What is

even: sym abt y-axis, f(x)=f(-x)

odd: sym abt origin, f(x)= -f(-x)

?

What did Lopez do right after Covid?

What is skydive?
3

The ones that aren't functions explain why specifically?

What is A & B are functions because every input has only one output? And also C fails because the input 0 has two different outputs and D fails because the input of a has two different outputs?

Where did Lopez go last summer and which artist did he catch in concert there?

What is Puerto Rico and Bad Bunny?

4


What is, No the student is not correct? 


The pairs are identical, the repeated input has the same output so it's the exact same point written twice

4

The problem "areas" for domain we have dealt with so far and how do we tackle them

What is the denominator of a fraction (set them equal to 0 so we can remove that input from our domain) and square root (we set everything under sqrt to ge0 because we can't have negative under square root?

4
What did Lopez do this 4th of July?

What is catch fireworks from the sky on a small plane?

5

Select the best answer and Explain why it's true and write the final list of points inside {}

What is option C?

Because the input 4 cannot have more than one output so a must equal 5 meaning the point just got repeated...  b,c ne 4 because that would lead to the input of 4 having more than one output.

5

And what is set x=o and find out what f(0) gives us for the y-int?
