If f(x)=5x^3 and g(x)=x+1 find (fxg)(x)

1 answer:

5 0

(f o g)(x) = f(g(x)) so we plug in the equation for g(x) where the x-variable is in f(x).

5(x + 1)³
5[(x + 1)(x + 1)(x + 1)]
5[(x² + 2x + 1)(x + 1)]
5(x³ + 3x² + 3x + 1)

(f o g)(x) = 5x³ + 15x² + 15x + 5

The dashed curve on the graph shows the initial function . What is the equation of the solid curve?

Jet001 [13]

Answer:

f(x) = sqrt(x + 6)

y = sqrt(x + 6)

x = sqrt(y + 6)

Stx^2 = y + 6

x^2 - 6 = y

red line: f(x) = sqrt(x + 6)

green line: f^-1(x) = x^2 - 6

A particular shoe store stocks two styles of walking shoes. Style A sells for $66.95 and Style B sells for $84.95. At the end of

Gnom [1K]

Answer:

Style A shoes sold : 152

Style B shoes sold : 88

Step-by-step explanation:

Let :

Style A shoes = x
Style B shoes = y

Forming equations :

x = 2y - 24
66.95x + 84.95y = 17,652

Substitute the value of x from 1 in 2.

66.95 (2y - 24) + 84.95y = 17,652
133.90y - 1606.80 + 84.95y = 17,652
218.85y = 19258.80
y = 88

Finding x :

x = 2(88) - 24
x = 176 - 24
x = 152

Solution :

Style A shoes sold : 152
Style B shoes sold : 88
