Answer:
f(-5)= 90, g(7)= -3x+4
Step-by-step explanation:
First Solve f(x)
f(x)= 3×^2-3x
Plug in -5 to the x
3(5)^2-3(-5)
f(x)= 90
Then Solve g(x)
g(x)=-3x+4
Plug in the 7 in the x
g(x)=-3x+4
g(x)=17
The total cost if Wacky Widget Company makes 230 widgets is $31,600.
<h3>What is the total cost?</h3>
The total cost is the sum of the rent (fixed cost) and the variable costs. The variable costs includes the cost of materials and labor.
