F(n+1)=f(n)-2 is the recursive function for this arithmetic sequence.  The explicit form is:

f(n)=a-d(n-1)  where a(initial term) is 10 and d(common difference) is -2

f(n)=10-2(n-1)  which cleans up to

f(n)=12-2n  so the first few terms are:

10,8,6,4,2,0,-2,-4.....

Which of the functions represents a linear function? Explain your reasoning, then determine the rate of change for that function
Andrej [43]

Answer:

Step-by-step explanation:

for Which of the functions represents a linear function? Explain your reasoning, then determine the rate of change for that function over the interval 2≤x≤4.

For a linear function, the rate of change is represented by the parameter m in the slope-intercept form for a line: y=mx+b, and is visible in a table or on a graph.

Consider the following quadratic equation. -4x^2+bx-11=0 Determine a possible value of b so that the quadratic has two complex s
romanna [79]

Answer:

Step-by-step explanation:

hello,

for ax^2+bx+c=0

\Delta = b^2-4ac

so here

\Delta = b^2-4*(-4)*(-11)=b^2-176

to have two complex solutions we need \Delta < 0\\

so b^2

b < \sqrt{176}=13.266...

for instance we can take b = 0

hope this helps
