Question

Given the function f(x) = 2x2 - 5x + 1. Calculate the following values: f(-2) = f(-1) = f(0) = f(1) = f(2) Question Hon

Answer 1

Given function is

`f(x)=2x^2-5x+1`

Substitute the value of -2 in the equation we get

`\begin{gathered} f(-2)=2(-2)^2-5*-2+1_{} \\ =8+10+1 \\ =19 \end{gathered}`

Similarly find other values

`\begin{gathered} f(-1)=2(-1)^2-5*-1+1_{} \\ =2+5+1 \\ =8 \end{gathered}`

And then similarly f(1)=-2 and f(2)=-1 and f(0)=1

`\begin{gathered} f(0)=2(0)^2-5*0+1_{} \\ =0+0+1 \\ =1 \end{gathered}`
`\begin{gathered} f(0)=2(0)^2-5*0+1_{} \\ =0+0+1 \\ =1 \end{gathered}`
