+x? How many zero pairs must be added to the function
f(x) = x2 - 10x - 4 in order to begin writing the function in
vertex form?

answer

a the answer hopes this

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
