The value of f(5) is 49.1
Step-by-step explanation:
To find f(x) from f'(x) use the integration
f(x) = ∫ f'(x)
1. Find The integration of f'(x) with the constant term
2. Substitute x by 1 and f(x) by π to find the constant term
3. Write the differential function f(x) and substitute x by 5 to find f(5)
∵ f'(x) = + 6
- Change the root to fraction power
∵ =
∴ f'(x) = + 6
∴ f(x) = ∫ + 6
- In integration add the power by 1 and divide the coefficient by the
new power and insert x with the constant term
∴ f(x) = + 6x + c
- c is the constant of integration
∵
∴ f(x) = + 6x + c
- To find c substitute x by 1 and f(x) by π
∴ π = + 6(1) + c
∴ π = + 6 + c
∴ π = 6.4 + c
- Subtract 6.4 from both sides
∴ c = - 3.2584
∴ f(x) = + 6x - 3.2584
To find f(5) Substitute x by 5
∵ x = 5
∴ f(5) = + 6(5) - 3.2584
∴ f(5) = 49.1
Answer:
Gaming can train your brain to make a fast decisions, can improve how you work with others in team-based environments, improve you motor skills, vision, balance, and dyslexia symptoms, reduce stress and anxiety overall, and even curb food and drug cravings. If all of this happens indirectly than it would make sense if modified videogames could solve the worlds problems

Step-by-step explanation:
<u>Given information</u>:
- Slope = 4
- Point on line = (-1, 2)
<u>Point-slope form</u><u> of linear equation</u>:
(where m is the slope and (x₁, y₁) is a point on the line)
Substitute the given slope and point into the formula:
<u>Slope-intercept form</u><u> of a linear equation</u>:
(where m is the slope and b is the y-intercept)
Substitute the given slope and point into the formula and solve for b:
Therefore:
<u>Standard form</u><u> of a linear equation</u>:
(where A, B and C are constants and A must be positive)
Rearrange the found slope-intercept form of the equation into standard form:
