Consider the polynomial function f(x)=3x²+8x-4. Find f(2).

Mathematics
1 answer:
Triss [41]3 years ago
5 0

Answer:

The value of polynomial for x = 2 that is f(2)  will be 32  

Step-by-step explanation:

We have given polynomial f(x)=3x^2+8x+4

We have to find the value of f(2)

We have to find the value of polynomial for x = 2

So for finding this value we have to just put x = 2 in polynomial

So f(2) will be f(2)=3\times 2^2+8\times 2+4=32

So the value of polynomial for x = 2 will be 32

Find the equation of the line that is perpendicular to y = –4x + 8 and passes though the point (–12, 4). A) y = – 1 4 x + 7 B) y
____ [38]

Answer:

Step-by-step explanation:

perp: 1/4

y - 4 = 1/4(x + 12)

y - 4 = 1/4x + 3

y = 1/4x + 7

answer is C

Which pairs of points would result in a line with a rate of change of 2:1? Select all that apply.
Helen [10]

Answer:

Options A, C, D are true.

Step-by-step explanation:

We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.

A. The points are (-4,-11) and (-2,-7).

Then the slope of the joining line is \frac{-7-(-11)}{-2-(-4)} =2

B. The points are (5,6) and (-5,12).

Then the slope of the joining line is \frac{12-6}{-5-5} =-\frac{3}{5}

C. The points are (0,-3) and (-4,-11).

Then the slope of the joining line is \frac{-11-(-3)}{-4-0} =2

D. The points are (0,-3) and (5,7).

Then the slope of the joining line is \frac{7-(-3)}{5-0} =2

Therefore, options A, C, D are true. (Answer)
