Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = (x + 6)(x - 3)
For x-intercept,
Substitute the value f(x) = 0.
(x + 6)(x - 3 = 0
x = 3, -6
So the x-intercepts will be,
(-6, 0) and (3, 0)
For y-intercept,
Substitute the value for x = 0,
f(0) = (0 + 6)(0 - 3)
= -18
Therefore, y-intercept of the given quadratic function will be (0, -18).

Step-by-step explanation:
<u>Step 1: Define</u>
(4x² - 2x - 3) + (-3x² + x + 7)
<u>Step 2: Simplify</u>
- Combine like terms (x²): x² - 2x - 3 + x + 7
- Combine like terms (x): x² - x - 3 + 7
- Combine like terms (Z): x² - x + 4

Given Situation: What is the percent increase from the 20 students to the 30 students.
Solution:
=> Let’s find how many percent did it increase.
Let’s have 20 as the first total number of the students in the first counts.
=> Then it became 30 students, let’s find out how many students added.
=> 30 – 20 = 10, there are 10 students added
10 is 50% of 20, thus, 50% added to the number of students. And that makes it 30 as the total count.
