G(x)=x2-3x valor de g(2.5)

g(2.5)=-1.25

Step-by-step explanation:

g=x^2-3x

g=2.5^2-3(2.5)

g=6.25-7.5

g=-1.25

 f(x) = 3x2 + 5 y y = 3x2 + 5

Correcto. Las expresiones que siguen f(x) = y y = son las mismas, por lo que estas son dos maneras distintas de escribir la misma función: f(x) = 3x2 + 5 y y = 3x2 + 5.

282 6/7 cm^2

step-by-step explanation:

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
