Evaluate: f(x) = 2x^2 + 6x - 4; f(-5) *
2 answers:

Find f(-5) by substituting x = -5 in the equation.

Therefore, the answer is f(-5) = 16
Answer:
f(-5)=126
Step-by-step explanation:
what you would do first is plug -5 in for x which would give you the equation of f(-5)= 2(-5)^2 + 6(-5) -4
then you multiply the negative 5 and you will get
f(-5)= -10^2 + 30 -4
remove that square by multiplying -10 by -10 and you will get
f(-5)= 100 + 30 -4
combine like terms and you will get
f(-5)=126
