Just substitute the values in.
if f (x)=-3x+1

a.) f (1)=-3(1)+1
solve.
-3(1)=-3+1=-2

b.) f(-2)=-3(-2)+1
-3(-2)=6+1=7

A. f(1) = -3(1)+1
= -3+1
= -2

b. f(-2) = -3(-2)+1
= 6+1
=7
for this question you just plug in the number given for x in the place of x in the equation and then you solve it as you usually do.

daser333 [38]

Answer:

c. 1/2

Step-by-step explanation:

7 out of 14 contestants did last time, which is 1/2 of the contestants.  You would assume that the same proportion would qualify when there are 10 contestants, so you would assume that 1/2 of 10 would also qualify for the bonus round.

Which shows one way to determine the factors of 12x3 – 2x2 + 18x – 3 by grouping?
Debora [2.8K]

Option A

2x^2(6x-1) + 3(6x-1) is one way to determine the factors of 12x^3-2x^2+18x-3 by grouping

<em><u>Solution:</u></em>

Factoring by grouping means that you will group terms with common factors before factoring

<em><u>Given expression is:</u></em>

12x^3-2x^2+18x-3

Group the first two terms together and then the last two terms together.

(12x^3-2x^2)+(18x-3)

We can see that 2x^2 is common in first two terms

And 3 is common in last two terms

Factor them out

(12x^3-2x^2)+(18x-3) = 2x^2(6x-1) + 3(6x-1)

2x^2(6x-1) + 3(6x-1)

Thus option A is correct
