Answer: f(g(x))= -2x+43
Step-by-step explanation:
Here, you would start by substituting the equation for g(x) into the x value of f(x) equation.
Since g(x)=1/4x+5, f(g(x)) would be:
f(g(x))= 3-8(1/4x+5)
Then you would simplify.
f(g(x))= 3-8(1/4x+5)
= 3-2x+40
=-2x+43
Answer:
30 grams
Step-by-step explanation:
if you subtract 70 from 100 you get 30.
Note that this is a quadratic function whose graph opens down. You could plot this function and note the coordinates of the vertex; the y-coordinate would be the max value of the function.
Alternatively, find x = -b/(2a), where a = -2, b = 8 and c = -5. Then find the corresponding y-value.
Alternatively, find the derivative of f(x) and set it = to 0. Solve for x. Find the y value associated with this x. That y-value is the max of f(x).
