The equivalent value of the function f(x) = –2x^2 – 3x + 5 if x = -3 is -4
We are to evaluate the function f(x) = –2x2 – 3x + 5 for the input value –3.
Given the function:
For x = -3, we will have to substitute x = -3 into the expression to have:
f(-3) = –2(-3)^2 – 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -18 + 14
f(-3) = -4
Hence the equivalent value of the function f(x) = –2x^2 – 3x + 5 if x = -3 is -4

Answer:
2.4 litres
Step-by-step explanation:
volume of a rectangular container = length x breadth x height/depth
volume of the rectangular container = 20cm x 12cm x 15cm
= 3600 cm³
volume filled with water = 2/3 x 3600 =2,400cm³
1000cm³ = 1 litre
therefore 2,400cm³ = 2400/1000 = 2.4 litres
