given f(x), evaluate f(4).\nf(x)=2x^{2}-6x + 17\nf(4)=?

Explanation:

Step1: Substitute (x = 4) into the function

(f(4)=2\times4^{2}-6\times4 + 17)

Step2: Calculate (4^{2})

(4^{2}=16), so (f(4)=2\times16-6\times4 + 17)

Step3: Perform multiplications

(2\times16 = 32) and (6\times4=24), then (f(4)=32-24 + 17)

Step4: Do additions and subtractions

(32-24=8), and (8 + 17=25)

Answer:

(25)
