Question

Find the slope of tangent y=2√x³+x

Answer 1

Answer:

The gradient (or slope) of the tangent to a curve at any particular point is given by the derivative at that point

If  

y

=

x

3

then  

d

y

d

x

=

3

x

2

When  

x

=

1

⇒

d

y

d

x

=

3

So the slope equals 3

Explanation:

Answer 2

Answer:

Explanation:

slope is given as dy/dx

so by differentiating

dy/dx=3rootx+1
