Math Problem Statement

Find the vertex of the function f(x) = -3x^2 + 12x - 10 and complete a table with values of f(x) for x = 1, 2, and 3.

Solution

To find the function values f(x)f(x) for x=1x = 1 and x=3x = 3, we will substitute these values into the given quadratic function:

f(x)=3x2+12x10.f(x) = -3x^2 + 12x - 10.

Step 1: Calculate f(1)f(1)

f(1)=3(1)2+12(1)10.f(1) = -3(1)^2 + 12(1) - 10. f(1)=3+1210=1.f(1) = -3 + 12 - 10 = -1.

Step 2: Calculate f(3)f(3)

f(3)=3(3)2+12(3)10.f(3) = -3(3)^2 + 12(3) - 10. f(3)=27+3610=1.f(3) = -27 + 36 - 10 = -1.

Now, we can complete the table:

x & f(x) \\ \hline 1 & -1 \\ 2 & 2 \\ 3 & -1 \\ \end{array}$$ Would you like a detailed explanation of these calculations or have any other questions?
