Answer:

25.

Step-by-step explanation:

The discriminant of ax^2 + bx + c = 0 is b^2 - 4ac.

2x^2 + x - 3 = 0

- the discriminant is  1^1 - 4*2*(-3) =  1 + 24

= 25  (answer).

Find the average rate of change of the function on the interval specified.
Gnom [1K]

The average rate of change of the function will be 63.

The average rate of change of the function is used to find the slope of the graphed function which can be calculated by the change in y value divided by the change in x value.

The average rate of change of function f(x) in the interval [a,b] can be calculated as avearge rate of change= (f(b)- f(a))/(b-a)

Here given function is g(x) = 7x³-4

which is defined in the interval [-3,3].

So using the defination of the average rate of change, The average rate of change= (g(3)-g(-3))/(3-(-3))

= {(7(3³)-4)-(7*(-3)³-4)}/(3-(-3))

= {(189-4)-(-189-4)}/(3+3)

= (185-(-193))/6

= (185+193)/6

= 378/6

= 63

Therefore the average rate of change of the function will be 63.
