The parent function of the function represented in the table is exponential.

Note if you subtract 10 from each output, you get $f(x)=3^x$ .

If function f was translated down 4 units, the f(x) values would be decreased by 4.

See attached image.

A point on the table for the transformed function would be (4, 87).

$f(4)-4=87$

Given the sequence 8, 12, 16, 20, 24, what is the sum of the 31st and 19th terms?

erica [24]

Answer:

First term (a) =8

Common difference (d)= t2-t1

=12-8

Now, sum of first 31th term (tn31) =n/2{2a+(n-1)d}

= 31/2{2×8+(31-1)4}

=31/2{16+(30×4)

=31/2(16+120)

=31/2×126

=31×63

Step-by-step explanation:

Similarly use 19 as (n) for the 19th term

(- 5x + 3y) (2x – 12y + 1) Multiply

Sonbull [250]

The answer for this problem i −10x2+66xy−36y2−5x+3y

Let's solve it by step by step.

(−5x+3y)(2x−12y+1)

=(−5x+3y)(2x+−12y+1)

=(−5x)(2x)+(−5x)(−12y)+(−5x)(1)+(3y)(2x)+(3y)(−12y)+(3y)(1)

=−10x2+60xy−5x+6xy−36y2+3y

So, -10x2+66xy-36y2-5x+3y

Determine all critical points for the following function. f(x)=x2−14x+1

melomori [17]

9514 1404 393

Answer:

(x, y) = (7, -48)

Step-by-step explanation:

A critical point is where the slope is zero or undefined. A polynomial function will never have any points where the slope is undefined.

The slope is zero were f'(x) = 0.

f'(x) = 2x -14

0 = 2x -14

0 = x -7

7 = x

f(7) = 49 -98 +1 = -48

The critical point is (7, -48).
