Pls help! evaluate f(4) on this table

Kruka [31]

Answer:

37

Step-by-step explanation:

f(4) just means use 4 for x. The table has all the x's across the top (sometimes they are in columns instead) The f(x) in the second row is the output that goes with each x. When x is 4, the f(x) is 37.

All is one math sentence:

f(4) = 37

During a Grand Prix car race, the tyres on a car are reduced in mass by 3%. If their mass is 388 kg at the end of the race, what

spayn [35]

Answer:

Their mass at the start was 400 kg.

Step-by-step explanation:

Given:

The tyres on a car during a grand prix race are reduced in mass by 3%. Their mass is 388 kg at the end of the race.

Now, to find the mass at the start.

<u>Let the mass at the start be $x$ .</u>

According to question:

$x - 3 \%ofx= 388$

⇒ $x-\frac{3}{100}\times x = 388$

⇒ $x-0.03x =388$

⇒ $0.97x=388$

<em>Dividing both sides by 0.97 we get:</em>

⇒ $x=400$

Therefore, their mass at the start was 400 kg.

The function g(x)=x^2+3. The function f(x)=g(x+2). The function f(x) is shifted horizontally how many places to where ? The func

STALIN [3.7K]

Answer:

The function f(x) is shifted 2 units to the left and 3 units up

Step-by-step explanation:

* Lets revise the translation of a function

- If the function f(x) translated horizontally to the right

by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left

by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up

by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down

by k units, then the new function g(x) = f(x) – k

* Lets solve the problem

∵ g(x) = x² + 3

∵ f(x) = g(x + 2)

- Lets find g(x + 2) by replacing x in g(x) by (x + 2)

∵ g(x) = x² + 3

∴ g(x + 2) = (x + 2)² + 3

∵ f(x) = g(x + 2)

∴ f(x) = (x + 2)² + 3

- The parent function of f(x) is x²

∵ x² changed to (x + 2)²

- Use the rules above

∴ f(x) is translated 2 units to the left

∵ (x + 2)² added by 3

- Use the rules above

∴ f(x) is translated 3 units up

* The function f(x) is shifted 2 units to the left and 3 units up
