    -7x+5x^2+10 f (-2) given

    -7 (-2) + 5 (-2) ^2+10 plug in - 2 where you see X

    14+5 (4) + 10 do (-2) ^2

    14+20+10 multiply 5 (4)

    45 add your numbers (this is the final)

    f (x) = - 7x + 5x² + 10

    f (-2) This means that x is - 2, so you plug in - 2 for "x" in the equation

    f (x) = - 7x + 5x² + 10

    f (-2) = - 7 (-2) + 5 (-2) ² + 10

    f (-2) = 14 + 5 (4) + 10

    f (-2) = 20 + 24

    f (-2) = 44
