Answer in explanation
Step-by-step explanation:
Before this we do this question let's get fimiliar with what's a function.
A function is a equation that when graphed, each input(x) correspond to one output(y). This means one inputs can't map to the diffrent output.
The vertical line test is just puting a vertical line anywhere on the function. If the vertical line touches more than two points your graph is not a function. If it touches one you graph is a function. The reason is because a vertical line that touches 2 points means one x maps to two diffrent y and thats not a function.
In conclusion the graph does pass the vertical line test so it is a function.

The evaluation of the expression gives -295/24. The correct option is the fourth option- negative 295 over 24 (-295/24)
<h3>Evaluating an Expression</h3>
From the question, we are to evaluate the given expression
The given expression is,
7 3/8 × -1 2/3
To solve the expression, we will covert the fractions from mixed to improper fractions
7 3/8 × -1 2/3
59/8 × - 5/3
Multiplying, we get
-295/24
Hence, the evaluation of the expression gives -295/24. The correct option is the fourth option- negative 295 over 24 (-295/24)

See the explanations below
Step-by-step explanation:
Given the function y = x²+12x
We are to find the inverse and identify the error in the calculation:
Step 1: Replace y with x
x = y²+12y
First Error: There is an error here y, the variable attached to x should be y and not x that is y = y²+12y and not y = y²+12x. The x should be totally replaced with
The second error is where he wrote y = √-11x
The square root of a value must return both negative and positive value not only the positive value. Hence the correct expression should have been y = ±√-11x (Note that the sign ± was introduced)
Third error: Since the value inside the square rot is a negative value hence the value of x must be negative i.e x must be less than zero not greater then. The correct inequality expression should have been <u>x <0</u> and not
x< 0
Answer:
The range is all real numbers.
Step-by-step explanation:
Range is simply all the y-values you could have when you substitute any given x-value.
Domain refers to all x-values that can be substituted into a function.
In the case of linear functions with a gradient, which are line equations, both the the domain and range are always "all real numbers" because any x-value can be substituted into the function and any y-value can be generated.
