Q. Find the

y

-coordinate of the

y

-intercept of the polynomial function defined below.

\newline

f(x)=9 x-4 x^{2}+9 x^{3}-3

\newline

Answer:

Evaluate at $x = 0$ : To find the $y$ -coordinate of the $y$ -intercept of the function $f(x)$ , we need to evaluate $f(x)$ at $x = 0$ , because the $y$ -intercept occurs where the graph of the function crosses the $y$ -axis, and this happens at $x = 0$ .
Substitute into $f(x)$ : Substitute $x = 0$ into the polynomial function $f(x) = 9x - 4x^2 + 9x^3 - 3$ . $f(0) = 9(0) - 4(0)^2 + 9(0)^3 - 3$
Simplify the expression: Simplify the expression by performing the operations. $f(0) = 0 - 0 + 0 - 3$
Final result: The result of the simplification gives us the y-coordinate of the y-intercept. $\newline$ $f(0) = -3$

Question

Tess tried to solve the differential equation

\frac{d y}{d x}=2 x y-6 x

. This is her work:

\newline

\frac{d y}{d x}=2 x y-6 x

\newline

1

\quad \frac{d y}{d x}=(y-3) 2 x

\newline

2

\quad \int \frac{1}{y-3} d y=\int 2 x d x

\newline

3

\quad \ln |y-3|=x^{2}+C_{1}

\newline

4

\quad e^{\ln |y-3|}=e^{x^{2}}+C_{1}

\newline

5

\quad|y-3|=e^{x^{2}}+C_{1}

\newline

6

\quad y-3= \pm e^{x^{2}}+C_{2}

\newline

7

\quad y= \pm e^{x^{2}}+C

\newline

Is Tess's work correct? If not, what is her mistake?

\newline

1

\newline

(A) Tess's work is correct.

\newline

1

is incorrect. We're not allowed to factor an expression when solving differential equations.

\newline

4

is incorrect. The right-hand side of the equation should be
