Question

For the function F defined by F(x)=x2−2x+4, find F(5). For the function F defined by F ( x ) = x 2 − 2 x + 4 , find F ( 5 ) . A. 32 32 B. 39 39 C. 19 19 D. 4

Answer 1

C. 19

Explanation:

Given the function defined by F(x)=x²−2x+4, in order to get f(5), we will have to simply substitute x = 5 into the formula given as shown;

F(5) = 5²-2(5)+4

F(5) = 25 - 10 + 4

F(5) = 15 + 4

F(5) = 19

Hence, for the function F defined by F(x)=x²−2x+4, F(5) = 19
