F(x) = (3x-5)(4x+2) <br> is the function linear or quadratic ?
Vikki [24]

Answer:

f(x)=(3x-5)(4x+2) is a quardatic function.

Step-by-step explanation:

f(x)=(3x-5)(4x+2)

simplify

f(x)=3x(4x+2)-5(4x+2)

f(x)=12x^{2} +6x-20x-10

adding the coefficients of x, we get

f(x)=12x^{2} -14x-10

which is quardatic equation since it contains the terms 12x^{2}.
