Please help asap I don't understand use the function f(x)=-x^2+8x-11, g(x)=14-2/3x, and h(x)=-x-7

1. f(-4) -f(1)
2. h(8)-2 · f(3)
3. 1/2g(-6)+f(-2)

the answer is 2/54

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
