Question

Difind the equation of curve

Answer 1

Answer:

Finding slope. To find the slope m m m of a curve at a particular point, we differentiate the equation of the curve. If the given curve is y = f ( x ) , y=f(x), y=f(x), we evaluate d y d x \dfrac { dy }{ dx } dxdy or f ′ ( x ) f'(x) f′(x) and substitute the value of x x x to find the slope.

Answer 2

Answer:

Correct answer:

x=−0.5

Explanation:

To find the x-intercept, we need to find the value of x when y=0.

So we first set y to zero.

y=4x+2

turns into

0=4x+2

Lets subtract 4x from both sides to move x to one side of the equation.

−4x=4x−4x+2

After doing the arithmetic, we have

−4x=2.

Divide by −4 from both sides

−4x−4=2−4

x=−0.5
