If
f ( x ) = 2 x 2 − 7 x + 4 \displaystyle {f{{\left({x}\right)}}}={2}{x}^{{2}}-{7}{x}+{4} f ( x ) = 2 x 2 − 7 x + 4 , find
f ′ ( − 2 ) \displaystyle {f}'{\left(-{2}\right)} f ′ ( − 2 ) .

Use this to find the equation of the tangent line to the parabola
y = 2 x 2 − 7 x + 4 \displaystyle {y}={2}{x}^{{2}}-{7}{x}+{4} y = 2 x 2 − 7 x + 4
at the point
( − 2 , 26 ) \displaystyle {\left(-{2},{26}\right)} ( − 2 , 26 ) .
The equation of this tangent line can be written in the form
y = m x + b \displaystyle {y}={m}{x}+{b} y = m x + b
where
m \displaystyle {m} m is:
