quester [9]
ax^2+bx+c=0\\\\x_1=\dfrac{-b-\sqrt{b^2-4ac}}{2a};\ x_2=\dfrac{-b+\sqrt{b^2-4ac}}{2a}


We\ have:\\\\15x^2+7x-12=0\\\\a=15;\ b=7;\ c=-12\\\\substitute\\\\x_1=\dfrac{-7-\sqrt{7^2-4\cdot15\cdot(-12)}}{2\cdot15}=\dfrac{-7-\sqrt{49-5(15)(-12)}}{30}\\\\x_2=\dfrac{-7+\sqrt{49-4(15)(-12)}}{30}

Serggg [28]

Answer:

f(x)=4x

Step-by-step explanation:

Given: See the attached image

To find: the function represented by the table

Solution:

A function is a relation in which every element of the domain has a unique image in the co-domain.

f(-2)=-8=4(-2)\\f(-1)=-4=4(-1)\\f(0)=0=4(0)\\f(1)=4=4(1)

Here, -2,-1,0,1 are elements in the domain and -8,-4,0,4 are elements in the co-domain.

Therefore, the table represents the function f(x)=4x
