Equation represents the graphed function.
What is a graphed function?
- Generating the graph (curves) of the appropriate function is the process of graphing a function.
- While graphing simple functions including linear, quadratic, cubic, etc. is fairly easy, complex functions like rational, logarithmic, etc. require some expertise and an understanding of certain mathematical ideas.
- Showing the curve that expresses a function on a coordinate plane is known as graphing a function.
- Every of the curve's points will satisfy the function equation if the curve (or graph) represents the function.
The general expression for a straight path is y=mx+c.
Since our graph's y-cut is at (0,3), the value of c is 3.
We then use the equation m=y2-y1/x2-x1 to calculate the gradient, which is "m" on the equation.
The equation is then obtained by replacing the m and c.

Answer:
P'(-3, -8), Q'(-6, 4), R'(1, -1)
Step-by-step explanation:
When you reflect a point (x, y) across the x-axis, the x-coordinate remains the same, but the y-coordinate gets the opposite sign: it becomes (x, -y).
Thus, if a point P, say, (-3, 8) is eightn units above the x-axis, its reflection P' will be the same distance below, at (-3, -8).
Thus, we get the following transformations.
P (-3, 8) ⟶ P' (-3, -8)
Q (-6, -4) ⟶ Q' (-6, 4)
R (1, 1) ⟶ R' (1, -1)
Thus, the vertices of the reflected triangle are P' (-3, -8), Q' (-6, 4), R' (1, -1).
The image below shows ∆PQR and its reflection ∆P'Q'R' across the x-axis.
Answer:
75
Step-by-step explanation:
If 75% of the students like skating, that means 35% of the students don't like skating.
35% of the students corresponds to 35 students that do not like skating.
Then to find the number of students who like skating we use the following logical computation,
35% represents 35 people then how much does 75% represent
⇒
=
Therefore,
The number of students who like skating was 75.
