Need help with exponential functions quick <br> 30 points
lisov135 [29]

Answer:

Since the independent variable x is not the exponent, y = - 7 x^{8} does not represent an exponential function.

Step-by-step explanation:

The general expression of an exponential function is f(x) = a^{x}, where a > 0 and a ≠ 1

Now the given function is y = - 7 x^{8} ..... (1)

So, we can say that the function f(x) = y is not an exponential function as x is not in power of any constant.

Therefore, since the independent variable x is not the exponent, y = - 7 x^{8} does not represent an exponential function. (Answer)

Find the coordinates of the points of intersection of the graphs with coordinate axes: y=− 1/4 x+2
bearhunter [10]

Answer:


Step-by-step explanation:

Here, you can use a simple formula.

To find the point of intersection you just put x=0 or y=0.

Because, if a graph intersects x-axis, then at this point  y=0

Similarly, if a graph intersects y-axis, then at this point  x=0


So, for our given line.

y=-1/4 x +2

when , x=0 , y=-1/4 (0)+2=2

So, the graph intersects y-axis at   y=2


when , y=0 ,

then    0=-1/4 x+2

       or, 1/4 x=2

       or, x=8    [multiplying by  4]

So, the graph intersects x-axis at   x=8
