Required

Find a and b

Using cosine formula, we have:

So, we have:

Make a the subject

So, we have:

Rewrite as:

This gives:

To solve for b, we use Pythagoras theorem

Collect like terms

Take positive square roots

i believe that the slope of the line is -5

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
