Given that f(x) = x – 2 and g(x) = x2 + 3x – 4, find (f – g)(x).

Svetradugi [14.3K]

Answer:

(f-g)(x)

= -x^2 - 2x + 2

Step-by-step explanation:

(f-g)(x) means

f(x) - g(x)

= x - 2 - (x^2+3x-4)

distribute the subtraction to all three of the last terms.

= x - 2 - x^2 - 3x + 4

combine like terms

= -x^2 - 2x + 2

Find the amplitude, phase shift, and period of the function. Give the exact values, not decimal approximations.y= -1+3cos(2x+pi/

antiseptic1488 [7]

The parts of a trigonometric function are:

$y=A\sin(Bx+C)+D$

Where:

A= Amplitude

2PI/B= Period

C= Phase

D= Shift

You have:

$y=3\cos(2x+\frac{\pi}{3})-1$

Amplitude= 3

Phase= π/3

Shift= -1

And the period:

$P=\frac{2\pi}{B}=\frac{2\pi}{2}=\pi$

The period = pi
