Answer:
Minimum of the function is -2.
Explanation:
Since we have to find the minimum value of the function which is a parabola, will open up and we have to find the value of y intercept.
The given function is g(x) = x²-18x + 79
We will convert the quadratic function in the form of f(x) = (x -h)² + k
Here k is the value on y-axis and the minimum value of the function.
g(x) = (x - 9)² - 2
So we can easily say the minimum will be -2.
Now we can confirm the answer by drawing the graph.
