Answer:

No, they will not intersect

Step-by-step explanation:

We are given a expression of the function f(x) as:

f(x)=\dfrac{1}{2}x^2+1

and the table of values for g(x) is given as:

x g(x)


1 −1


2 −2


3 −3

i.e. the function is given as:

g(x)=-x

Also we can find the equation of g(x) by the slope intercept form i.e. y=mx+c

Here y=g(x)

When x=1 y=-1

this means -1=m+c-----(1)

And when x=2 y=-2

-2=2m+c------(2)

On solving the above two equations i.e. eqn(1) and (2) by method of elimination we have:

m=-1 and c=0

Hence y=g(x)=-x

From the graph of f(x) and g(x) we could clearly see that the graph of two functions do not intersect at any point in the coordinate plane.

Hence, last option is correct.

No, they will not intersect

If George's bike weighs 15 pounds, then we can say that because Obed's bike is 3 pounds heavier than George's, Obed's bike weighs 18 pounds. If Obed's bike weighs 18 pounds, then we can say that because Elsa's bike is twice as heavy as Obed's, Elsa's bike weighs 9 pounds.

It is 102.5. You made it kind of confusing at first by putting the divisor first in your question then putting your dividend, but I understand what you meant.
