What is (f−g)(x)? f(x)=x^4−x^2+9 g(x)=x^3+3x^2+12 (f−g)(x)=

wlad13 [49]

Answer:

x^4 -x^3 -4x^2-3

Step-by-step explanation:

f(x)=x^4−x^2+9

g(x)=x^3+3x^2+12

(f−g)(x)= x^4−x^2+9 - (x^3+3x^2+12)

Distribute the minus sign

(f−g)(x)= x^4−x^2+9 - x^3-3x^2-12

I like to line them up vertically

x^4 −x^2+9

- x^3 -3x^2-12

I WILL GIVE BRAINLIEST AND THANKS SOLVE THE EQUATION

lord [1]

Answer:

x = -5.83, -0.17

Step-by-step explanation:

Quadratic Formula: $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

Since we are given a = 1, b = 6, and c = 1 from our quadratic, we use the Quadratic Formula:

Step 1: Plug in variables

$x=\frac{-6+/-\sqrt{6^2-4(1)(1)} }{2(1)}$

Step 2: Solve

$x=\frac{-6+/-\sqrt{36-4} }{2}$

$x=\frac{-6+/-\sqrt{32} }{2}$

Step 3: Evaluate to decimals

When you do so, you should get x = -5.82843 and -0.171573

Help I don't know how to do this

Vilka [71]

Answer:

P(t) = 282.2(1.009)^t

Step-by-step explanation:

Look at the attached image.

Hope you can read my handwriting. the image cut off the right side, b = 1.009213324... but question asks to round to nearest thousandth so it's 1.009

For the second part just use the equation to find P when t = -1 and see if P is less than (underpredicts) the number from the question or greater than (overpredicts) the number. I haven't calculated it but I think it will be smaller and thus underpredicts just from looking at the numbers when t = -1
