Answer:
f(3) = -20
Step-by-step explanation:
To find the value of a function, substitute the number for the variable and do the arithmetic.
f(x) = -2x^2 +x -5 . . . . . . given
f(3) = -2(3^2) +(3) -5 . . . . function value for x = 3
f(3) = -2(9) +3 -5 = -18 +3 -5
f(3) = -20
Answer:
D
Step-by-step explanation:
Suppose she only fills her big pots. The number of big pots filled is 120÷12=10. So the y-intercept is (0,10).
Now suppose she only fills her small pots. The number of small pots filled is 120÷5=24. So the x-intercept is (24,0)
