If f(x)=2x-1 and g(x)=x^2-4, what is g(f(x))
lesantik [10]

Answer:

4x^2 - 4x - 3

Step-by-step explanation:

f(x) = 2x - 1

g(x) = x^2 - 4

g(f(x)) = ?

[substitute the x of g(x) with f(x)]

g(x) = x^2 - 4

g(f(x)) = (2x - 1)^2 - 4

[solve]

[binomial * binomial = quadratic equation]

[use FOIL method (first, outer, inner, last)]

g(f(x)) = (2x - 1)(2x - 1) - 4

g(f(x)) = (2x*2x) + (-2x) + (-2x) + (1) - 4

[combine like terms]

g(f(x)) = 4x^2 - 2x - 2x + 1 - 4

g(f(x)) = 4x^2 - 4x - 3

you download a video game on your computer. you have a 60-minute free trial of the game. it takes 5 1/6 minutes to set up the ga
iren2701 [21]

Answer:

B. 5\frac{1}{6}+(7\frac{1}{3})l \leq 60

Step-by-step explanation:

Given,

The time for set up the game = 5\frac{1}{6} minutes,

Also, the time for each level of game is 7\frac{1}{3} minutes,

If there are l levels of games,

Then the time taken in all levels of game = (7\frac{1}{3})l

Hence, the total time ( in minutes ) = Set up time + time in all level

= 5\frac{1}{6}+(7\frac{1}{3})l

We have 60-minute of free trial of the game,

So, the total time taken can not be exceed to 60 minutes,

\implies 5\frac{1}{6}+(7\frac{1}{3})l \leq 60

Which is the required inequality.

Option 'B' is correct.

If y=3x+5 and z=x^2+2x-5, what is yz?
Hitman42 [59]
<h3>Answer:  3x^3 + 11x^2 - 5x - 25</h3>

Work Shown:

yz = y(x^2+2x-5)

yz = y(x^2) + y(2x) + y(-5)

yz = x^2( y ) + 2x( y ) - 5( y )

yz = x^2( 3x+5 ) + 2x( 3x+5 ) - 5( 3x+5 )

yz = x^2*3x + x^2*5 + 2x*3x + 2x*5 - 5*3x - 5*5

yz = 3x^3 + 5x^2 + 6x^2 + 10x - 15x - 25

yz = 3x^3 + 11x^2 - 5x - 25
