Question

What is the 3 correct answers?

Answer 1

Here is notation

• If a function be ax^2+bx+c
• c is the y intercept

Now our answers are

1. -5
2. 8
3. -11

Answer 2

The given functions are written in the standard form:

$\tt \to \: ax ^{2} + bx + c = 0$

Where,

• C is the y-intercept

Now,

#1

$\sf : \implies \: y = {1x}^{2} + 7x - 5$

Here,

• C = -5
• I.e. y-intercept is -5

#2

$\sf : \implies \: y = {1x}^{2} - 3x + 8$

Here,

• C = 8
• I.e. y-intercept is 8

#3

$\sf : \implies \: y = {1x}^{2} - 15x - 11$

Here,

• C = -11
• I.e. y-intercept is -11
