What is the minimum value for g(x)=x2−18x+79?

Minimum of the function is -2.

Step-by-step 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.
