Question

if fx(x)=x^2-3x^2+5,find f(0)+f(3)​

Answer 1

Answer is 8

Step-by-step explanation:

Given, $f(x) = x^2 - 3x^2 + 5$

• $f(x = 0) = f(0) = (0)^2 -3(0)^2 + 5$

= 5

• $f(x = 1) = f(1) = (1)^2 -3(1)^2 + 5$

= 1 - 3 + 5

= 3

• $and\ f(x = 3) = f(3) = (3)^2 -3(3)^2 + 5$

= 9 - 27 + 5

= - 13

Hence, f(0) + f(3) = 5 - 13

= - 8
