how to draw functions on a coordinate plane, and he mentioned something about the Y-Intercept being an important step in creating/solving a function. But, what exactly is a Y-Intercept?

The y-intercept of a function

f (x)

is the point where the function intersects the y-axis (if in fact it does intersect the y-axis) and it is found by evaluating

f (0)

, i.e., finding the value of

f (x)

when

x = 0

.
For example,
- The line

f (x) = y = 3 x + 2

intersects the x-axis at when

x = 0 :

:when

y = 3 \cdot 0 + 2 = 2

. This is the function's y-intercept.
- The parabola

f (x) = y = 2 x^{2} + 8

intersects the y-axis when

x = 0 :

:when

y = 2 (0)^{2} + 8 = 8

. This is the function's y-intercept.

An equation to the tangent line of

h (x) = \tan (x) + \cos (x)

is given by

y = m x + b

where

m

is the slope and

b

is the

y

-intercept. If

x = \frac{π}{4}

find

m

Two questions involving quadratics. Next to a diagram of a parabola with a ma point with the y intercept of

(0, p)

and roots

(- 1, 0)

and

(p, 0)

it says:3a) Show that the equation of the parabola is

y = p + (p - 1) x - x^{2}

3b) For what value of

p

will the line

y = x + p

be a tangent to this curve.

Find: vertex,

y

-intercept,

x

-intercepts (if any), axis of symmetry
What I have so far:
Vertex:

(- 4, - 2)

y

-intercept:

(0, 2)

x

-intercept:

2

Axis of symmetry

The gradient is

m = - 4 / 3

, and the point given is

(3 / 2, 3)

Let

c

be the

y

-intercept

y = m x + c

y = (- 4 / 3) x + c

If I substitute

x

and

y

from the point given,

3 = (- 4 / 3) (3 / 2) + c

and look for

c

, I get

c = 5

But according to my answer sheet,

c = 33 / 8

by using

y - y_{1} = m (x - x_{1})

Why are the two methods giving different answers?

This is equation of a curve

\sqrt{y} + \sqrt{x} = \sqrt{A}

A

is a positive constant

T

is a tangent of the curve from any point on it

B

is the y-intercept of

T

C

is the x-intercept of

T

Prove that

B + C = A .

Find the

y

-intercept of the curve that passes through the point

(2, 1)

with the slope at

(x, y)

of

\frac{- 9}{y^{2}}

\frac{d y}{d x} = \frac{- 9}{y^{2}}

\int y^{2} d y = \int - 9 d x

\frac{y^{3}}{3} = - 9 x + C_{1}

y^{3} = - 27 x + C

(C = 3 C_{1})

y = (- 27 x + C)^{1 / 3}

1 = (- 27 (2) + C)^{1 / 3}

C = 54

0 = (- 27 x + 54)^{1 / 3}

y - i n t e r c e p t = (- 2, 0)

Where is mistake?
