PLEASE HELP Given the function f(x) = 3x2 – 4

Mathematics
1 answer:
Zarrin [17]2 years ago
7 0

Answer:

15

Step-by-step explanation:

Rate of change is the slope of the tangent which will be the derivative of the function

if f(x) = 3x² - 4

f'(x) = 6x

as the derivative is linear, the average rate of change will occur at the midpoint of the interval

f'(2.5) = 6(2.5) = 15

This is simple,

Step-by-step explanation:

If the bus costs 200$ and the fair charges 4$ per students that means you have to do this:

Cual es la ecuacion lineal de estos infinita solucion o no solucion<br>​
coldgirl [10]

Cuando has simplificado la ecuación lo mas posible y las expresiones de los dos lados quedan iguales, hay soluciones infinitas.  Pero, dado que lo has simplificado y son diferentes, no hay solución.

1.) 7x = 12 + 7x - 12

=> 7x = 7x => infinita solución

2.) x - 11 = 11 + x

=> x = 22 + x => no solución

3.) 2(4x - 6) = 8(x + 2)

=> 8x - 12 = 8x + 16 => 8x = 8x + 28 => no solución

4.) 2x - 9 = 2x - 9

=> infinita solución

5.) 8 + 4x = 4x + 10

=> 4x = 4x - 2 => no solución
