Let f(x)=2x^2+x-3 and g(x)=x-1. Perform the indicated operation, then find the domain.

1 answer:

5 0

Multiplying the two functions together using the Distributive Property, we get (2x²+x-3)*(x-1)=2x³+x²-3x-2x²-x+3= 2x³-x²-4x+3. In addition, since any value x can be plugged into 2x³-x²-4x+3, A is your answer!

Pls help many thanks

salantis [7]

So, let's make these two values improper fractions so they're easier to work with. $4+\frac{1}{3}=\frac{12}{3}+\frac{1}{3}=\frac{13}{3} 3+\frac{1}{2}=\frac{6}{2}+\frac{1}{2}=\frac{7}{2}$

So, to get the rate he grew in those months we have:

$\frac{\frac{13}{3} \text{inches}}{\frac{7}{2}\text{months}} =\frac{26\text{inches}}{21\text{months}}$

And to get the rate he grew in one month we have to divide both our numerator and our denominator by 21 to get:

$\frac{\frac{26}{21} \text{inches}}{\text{month}}\approx \frac{1.24\text{inches}}{\text{month}}$ aka he grew 1.24 inches in a month.

Fred takes 3 hours to dig a garden. It takes Jason 5 hours to

Irina18 [472]

It takes them 1 7/8 hrs to complete the job together.

How:
Fred = 3 hrs
Jason = 5 hrs

1/3x + 1/5x = 1/x

3x x 5x = 15 —> 3x/15 + 5x/15 = 15/15

3x + 5x = 8x —> 8x/15 = 1.875 = 1 7/8 hrs
