The table shows a linear function. <br><br> Which equation represents the function.

mote1985 [20]

Answer:

$\large\boxed{f(x)=\dfrac{3}{2}x-1}$

Step-by-step explanation:

$\text{The slope-intercept formula:}\\\\y=mx+b\\\\m\ -\ slope\\b\ -\ y-intercept\\\\\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{From the table we hve two points (0, -1) and (2, 2). Substitute:}\\\\m=\dfrac{2-(-1)}{2-0}=\dfrac{3}{2}$

$\text{Therefore the equation is}\ f(x)=\dfrac{3}{2}x-1\\\\\text{Check for the point (4, 5):}\\\\f(4)=\dfrac{3}{2}(4)-1=(3)(2)-1=6-1=5\qquad\ CORRECT$

1. f(-6)=12

2. k(-4)=-68

Further explanation:

We have two functions whose values we have to find on certain points.

In order to find the values of function, the value is put in place of variable in the function.

So,

<u>1. f(a) = -2a</u>

We have to find, f(-6)

So putting -6 in function

$f(-6) = -2(-6)\\= 12$

<u>2. k(x) = -3x^2+5x</u>

We have to find, k(-4)

So putting -4 in function

$k(-4)=-3(-4)^2+5(-4)\\=(-3)(16)-20\\=-48-20\\=-68$
