Answer:
(0,5)
Step-by-step explanation:
Y intercept is where line touches y axis so x = 0.
(0,5) since it's only 5 and the others don't count.
Use dot product
a=(x1,y1) and b=(x2,y2)
a.b=/a/*/b/ cos x
a.b mean dot product of two vectors
a.b is equals x1*y1+x2*y2
Answer:
y = 1.
Step-by-step explanation:
f(x) = x^2 + 1
We know that:

replacing the function, we get:

Now we can simplify this to:

and solving the quotient, we get:

then f'(x) = 2*x
And we want the equation for the tangent line at (0, 1)
The slope of that line will be:
f'(0) = 2*0 = 0
So this is a horizontal line, of the type y = a
And we know that this line must pass through the point (0, 1)
so we must have y = 1.
Then the equation of the tangent line to f(x) at the point (0, 1) is:
y = 1.
