The solution of the expression is 38
How to solve the expression
The expression −1 * f(−9) + 7⋅* g(6) is solved using the information from the graph, to get the values, then applying PEMDAS to perform the calculation
From the grave we have that
f(−9) = 4 and
g(6) = 6
plugging in these values
= −1 * f(−9) + 7⋅* g(6)
= −1 * 4 + 7⋅* 6
= -4 + 42
= 38
