Question

This is Algebra 1 functions and I'm struggling with this one function-

-1•f(-9)+7•g(6)=_____

​

Answer 1

38

Explanation:

f(-9) is the value of f(x) when x = -9. Therefore, f(-9) = 4 from the graph. Doing the same with g(6), we can see that g(6) = 6. Our expression becomes:

-1 * 4 + 7 * 6

= -4 + 42

= 38
