Solution

## For any quadratic expression y=f(x)=ax2+bx+c, the y− intercept is given as the value of f(0). Using this, let's find out the y intercepts for the given quadratic expressions. A.y=f(x)=3x2−4x+2 It's y− intercept will be f(0)=2 B.y=f(x)=(4x−1)(2x+1) It's y− intercept will be f(0)=(4×0−1)(2×0+1)=−1 C.y=f(x)=(4x−3)2 It's y− intercept will be f(0)=(4×0−3)2=9 D.y=f(x)=−(2x+3)2+9 It's y− intercept will be f(0)=−(2×0+3)2+9=0
