The function's input value is 2.
f(x) = 2x² + 3x + 5
f(x) = 2(2)² + 3(2) + 5
f(x) = 2(4) + 6 + 5
f(x) = 8 + 11
f(x) = 19
Answer: 225km
Step-by-step explanation:
3cm --- 150
1cm ---- 50
Therefore 4.5cm * 50 = 225km
We have to find the output values for the given input values of the function given as,
Here, x = Input value of the function
And f(x) = Output values
By substituting the input values of x as,
For x = -4,
f(-4) = -4(-4) - 5
= 16 - 5
= 11
For x = 1,
f(1) = -4(1) - 5
= -4 - 5
= -9
For x = 3,
f(4) = -4(3) - 5
= -17
For x = 11,
f(11) = -4(11) - 5
= -44 - 5
= -49
Therefore, Option (A) will represent the output values for the given input values.
