Answer:

Option C and E

Step-by-step explanation:

A linear function is represented by a straight line when graphed.

Linear function means a straight line with uniform rate of change.

A.   The temperature rises and falls means rate of change is not uniform.  So the function representing temperature as a function of time is not a linear function.

B.    A base ball was hit into outfield which achieved maximum height but goes down. So rate of change in height is not uniform so function representing height as a function of time is not linear.

C.    Car goes 55 mph on the highway so change in distance with respect to time will be a linear function.

D.    A child grew 2 inches this year and 1 inch last year so rate of change in height will not be a linear function.

E.    Movie director makes 2 movies per year. The number of movies represented by a function in terms of years will be linear showing a straight line.

Option C and E are correct.

In which direction does the graph of the function shown below open?
sp2606 [1]

Answer:

D. Up

Step-by-step explanation:

When a parabola has the form  y=ax^2+bx+c , It is vertical (opens up or down).

Because the variable "x" is squared.

If  "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.

In this case you have the quadratic function:

f(x) = 2x^2+5x-4

Which can be rewritten as:

 y = 2x^2+5x-4

Therefore, it is vertical, because it has the form:  y=ax^2+bx+c

You can observe that the value of "a" is:

a=2

Then, since "a" is positive, the parabola opens up.
