Math Problem Statement
Let's compute ( F(-1) ) given the function ( F(x) = 5x^2 - 10x + 21 ).
Given ( x = -1 ): [ F(-1) = 5(-1)^2 - 10(-1) + 21 ]
First, calculate ( (-1)^2 ): [ (-1)^2 = 1 ]
Next, substitute and compute: [ F(-1) = 5(1) - 10(-1) + 21 ] [ = 5 + 10 + 21 ] [ = 36 ]
Therefore, ( F(-1) = 36 ).
