Answer:
if f(x)= -4x+3
f(-5)= 23
Step-by-step explanation:
first you substitute x for -5
f(-5)= -4(-5)+3
then you multiply
-4(-5)
f(-5)=20+3
you get the positive 20 because negative times negative equals positive
then you just add the rest (20+3) which will give you your answer
f(-5)= 23

Answer:
C. -3(√y)(∛x²)
Step-by-step explanation:
Recall the rule for exponents with fractions. The numerator represents the power the variable is raised by, and the denominator represents the which root will be taken.
y^1/2 equals √y
and x^2/3 equals ∛x²
So the answer is -3(√y)(∛x²)
