8 0

Answer:

2x^{2}-x

Step-by-step explanation:

To find (x+1) substitue x+1 into the function.

1. 2(x+1)^2-5(x+1)+3: Substitution

2. 2x^2+4x+2-5x+5+3: First do binominal expansion theorem for 1st one then distrubtive property for the first and second one.

3.Combine like with like

2x^{2} , 4x+(-5x)= -x,  2-5+3=0 so

f(x+1)= 2x^{2}-x

Y= -1/2x-3 <br> Plot the x- and y-intercepts to graph the equation.
viva [34]

Answer:

Graph is attached below

Step-by-step explanation:

Intercepts are values of x and y at which the graph of the function intersects coordinate axis.

Given equation,

y=-\frac{1}{2}x - 3

For x-intercept,

y = 0,

\implies 0 =-\frac{1}{2}x - 3

3 =-\frac{1}{2}x

\implies x =-6

Thus, x-intercept is at (-6, 0)  

For y-intercept,

x = 0,

\implies y =-\frac{1}{2}(0) - 3=-3

Thus, y-intercept is at  (0, -3)

Now, join these two points to show the line in coordinate plane.
