Answer:

And on this case we can use the product rule for a derivate given by:

Where
and
And replacing we have this:

Step-by-step explanation:
We assume that the function of interest is:

And on this case we can use the product rule for a derivate given by:

Where
and
And replacing we have this:

You need help with what problem
Start by integrating y'' twice to get function y(x).

Next find value of coefficients 'c' and 'd' using the given tangent line
The slope of tangent line is equal to y' when x=1.

The tangent line intersects the curve y(x) when x = 1.
If x = 1, then y = 4 (From y =-x+5)

Final Answer:
Solid is if x is greater/less than or equal to (there isn’t a symbol for it) the line and the line would be dashed if x is < or > something
Okay to have a complete triangle with 3 angles it must add up to 180° So therefore if you have 30° For each angle which adds up too 90°. We're are still missing 90 more degrees. So that means we can't make a triangle at all.
