What it the x and y intercept of y=2x^2+3x+1
castortr0y [4]

What you have here is a quadratic polynomial.

The form is: ax^2 + bx + c


C is ALWAYS the y-intercept in non-linear polynomials. So we immediately know the y-intercept to be 1.


For the X-intercept(s), we can solve in a few ways, but let's use the quadratic formula.


The quadratic formula states that y=-b+-((sqrt(b^2-4ac) / 2a).

A = 2

B = 3

C = 1

Plug in your information,

\frac{-3 \frac{+}{-} \sqrt{3^2 - 4(2)(1)} }{2(2)} \\\sqrt{9 - 8}\\ \sqrt{1} \\\\\frac{-3 \frac{+}{-} 1}{4}


y = (-3 +- 1) / 4


X = -.05

X = -1

Y = 1


X-Intercepts: -.05, -1

Y-Intercepts: 1

Solve the system by graphing.<br> What is the solution of y=-x+4 and y=3/5x+4
dlinn [17]

Answer:

x=0 and y=4 thats where the points meet

Step-by-step explanation:

solution of x and y:

both equations equal to y so you can put them together

3/5x+4=-x+4

separate the variables and numbers...

1.6x=0

x=0

y=4

if ur using a graph, use the y intercept (0,4) for your first point

then, using y=-x+4, make -x a fraction -1/1

by using rise/run go down one unit from (0,4) since its negative 1

then one unit to the right from where you are

you should be able to connect the points for the first equation

find the second equation on your own now:)
