Question

if f (x) = 2x2+3x+2 then find the value of f (2)​

Answer 1

Step-by-step explanation:

Given f(x+1)=2x

2

−3x+1 ……..(1)

Now, to find f(x+2) let us

put (x+1) in place of 'x' in (1)

or, f(x+2)=2(x+1)

2

−3(x+1)+1

=2(x

2

+2x+1)−3(x+1)+1

=(2x

2

+x).

Answer 2

Answer:

=> 16

Step-by-step explanation:

Given that:-

$f(x)=2x^2+3x+2$

As we have to find the value of f(2),

For calculating the value of f(2), we have to put the value of 2 in the above expression as x:

As we have,

=> $f(x)=2x^2+3x+2$

=> $f(2)=2(2)^2+3(2)+2$

By further simplifying it we get,

=> $f(2)=8+6+2$

=> $f(2)=16$

Hence, the value of f(2) is 16.
