2.2.4 Fitting Linear Models to Data (a/p-e!x)

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)

ѕнє ¢αи ∂яινє 132 кιℓσмєтєяѕ

нσρє ι ¢συк∂ нєℓρ

the value of x is 90 - 20 aka 70*, these are complementary angles
