notka56 [123]

Answer:

Find the maximum value of the function f(x) = -0.7x2 – 2.7x + 4 to the nearest hundredth.
Irina18 [472]

We need range

\\ \sf\longmapsto f(x)=-0.7x^2-2.7x+4

  • See here x^2 will come greater than or equal to zero.

Least value of x^2 is 0

\\ \sf\longmapsto -0.7(0)+2.7(0)+4=4

So

range

\\ \sf\longmapsto R_f=[4,\infty)
