The derivative of a function f(x) is given by f'(x)=3x^2-6x+4. The tangent line at the point (2,9) is parallel to another tangen
ArbitrLikvidat [17]

Answer:2

Step-by-step explanation:

Given

The derivative of a function is f'(x)=3x^2-6x+4

The slope at (2,9) is

\Rightarrow 3(2)^2-6\times 2+4=4

the tangent at (2,9) is parallel to another tangent at (a,b) i.e. their slopes are equal

\Rightarrow 4=3a^2-6a+4\\\Rightarrow 3a^2-6a=0\\\Rightarrow\ 3a(a-2)=0\\\Rightarrow a=0\ \text{or}\ a=2
