Answer:
f(x) = 4 when x is 8
Step-by-step explanation:
Domain is the set of x values that make the function defined. Allowed x values for the function (mapping).
The Range is the set of y values that make the function defined. Allowed y values for the function (mapping).
- Whenever we need to find f(a), suppose, then we look for "a" in the domain and see its corresponding value mapping in the range.
- Whenever we will be given a value for f(x) = a, suppose, and we have to find "x", we look at the value a in the range and find corresponding x value in the domain.
Firstly, we need f(4), so we look for "4" in domain and see which number it corresponds to in range.
That is
Thus,
Next,
We want "x" value that gives us a "y" value of 4. We look for "4" in the range and see which value it corresponds to. That is "8". So,
f(8) = 4
rule is to shift 8 units left & , shift 2 units down , Correct option C) T<-8,-2> (Jessica) ,
<u>Step-by-step explanation:</u>
Here we have , Jessica was sitting in row 9, seat 3 at a soccer game when she discovered her ticket was for row 1, seat 1. We need to Write a rule to describe the translation needed to put her in the proper seat. Let's do this:
Suppose the above problem in coordinate system where we have a point , And we need to write rule for translation of this point to
.
Let , , Now shift 8 units left i.e.
⇒
⇒
⇒
Now , shift 2 units down i.e.
⇒
⇒
⇒
Therefore , rule is to shift 8 units left & , shift 2 units down , Correct option C) T<-8,-2> (Jessica) ,
Answer:
The diameter of an extra large pizza from Gambino's Pizzeria is
Step-by-step explanation:
we know that
The area of a circle (circular pizza ) is equal to
we have
substitute in the formula and solve for the radius r
Simplify
Find the diameter
Remember that the diameter is two times the radius
