Express the quadratic function in standard form.
f(x) = −x2 + 10x + 1
f(x) = 2x2 − 16x + 38
f(x) = x2 + 2x – 4
f(x) = 5x2 − 10x + 1
f(x) = −x2 − 3x + 3
f(x) = 2x2 − 12x + 19

Question

Express the quadratic function in standard form.
f(x) = −x2 + 10x + 1
f(x) = 2x2 − 16x + 38
f(x) = x2 + 2x – 4
f(x) = 5x2 − 10x + 1
f(x) = −x2 − 3x + 3
f(x) = 2x2 − 12x + 19

anonymous · Answer

standard form is a.x^2 + b.x + c
so now just check from your questions  the value of a, b and c

like for the first one,

f(x) = - x^2 +10.x + 1

a= -1 , b= 10 , c =1

i have to put them in standard form. 
like f(x) = x^2 − 6x 
is f(x)=(x-3)^2-9
