The sum of 5 and twice a number

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

5/20 so 25%

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
