$y=x^2$

When $x=4$, $y=4^2=16$

The gradient function $=2$x

$\therefore$ the gradient $=8$, when $x=4$

$\therefore$ the point is $(4,16)$, and the gradient is $8$.

When $x=-10$, $y=x^2=+100$

The gradient function $=2x=-20$

$\therefore$ the point is $(-10, 100)$, and the gradient is $-20$.

Your Answer

Surround your text in *italics* or **bold**, to write a math equation use, for example, $x^2+2x+1=0$ or $$\beta^2-1=0$$

Use LaTeX to type formulas and markdown to format text. See example.
