Question

What is f(5) for f(x)=4x^2-5x+2? A)-24 B)77 C)127 D)150

Answer 1

Answer:

B. 77

Step-by-step explanation:

Just change all the "x" with 5.

So, it'd be like

f(x) = $4(5)^{2} - 5(5) + 2$

f(x) = 77

Answer 2

Answer:

B)77

Step-by-step explanation:

f(x)=4x^2-5x+2

Let x=5

f(5) = 4(5)^2 -5(5) +2

     = 4*25 -25 +2

     =100 -25+2

     =75+2

     =77
