find function values f(x)=9x^2+10x-8
To find the function values of f(x) = 9x^2 + 10x - 8, you need to substitute values of x into the function and calculate the corresponding y-values.
Let's go step by step:
1. Start with the function f(x) = 9x^2 + 10x - 8.
2. Choose a value of x. For example, let's say x = 2.
3. Substitute the value of x into the function:
f(2) = 9(2)^2 + 10(2) - 8
= 9(4) + 20 - 8
= 36 + 20 - 8
= 48 - 8
= 40.
So, when x = 2, the function value f(x) is 40.
4. Repeat steps 2 and 3 for any other values of x that you want to find the function values for.
