If f(x) = 2x - 1 and g(x= 3x + 5, what is f(g(-

The answer to this question is -21.

Step-by-step explanation:

f(g(-3)) says "f at g at -3".

"Evaluating  the value of g if x is -3, Then put the value of  x into the f function".

g(x) = x - 4

g(-3) = 3x +5

g(-3)=3*(-3)+5

g(-3)=-15+5

g(-3)=-10.

put -10 into the f.

f(x)=2x-1

f(-10)=2*(-10)-1

f(-10)=-20-1

f(-10)=-21.

so f(g(-3))=-21.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
