Find the difference of functions s and r shown below. r(x) = -x² + 3x s(x) = 2x + 1 ( s-r)(x)=​
drek231 [11]

Answer:

Part 1)

(s-r)(x)=(2x+1)-(-x^2+3x)

Part 2)

(s-r)(x)=x^2-x+1

Step-by-step explanation:

Part 1)

So we have the two functions:

r(x)=-x^2+3x\text{ and } s(x)=2x+1

And we want to find:

(s-r)(x)

This is the same as:

=s(x)-r(x)

Substitute:

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

So, our answer for Part A is:

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

Part 2)

Let's find our difference.

Distribute the -1:

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

Combine like terms:

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

Add:

=x^2-x+1

And we're done!

If g(x) = 3/2x + 3, and g(a) = 0, what is a ?
Lostsunrise [7]

Answer:

a = -2

Step-by-step explanation:

g(x) = 3/2x + 3

g(a) = 0

g(a) = 3/2a +3 =0

Subtract 3 from each side

3/2a +3-3=0-3

3/2a = -3

Multiply each side by 2/3

2/3 * 3/2a = -3*2/3

a = -2
