Which graph represents the function f(x)= 0.2^x + 3

The third graph or bottom left graph represents f(x) = 0.2^{x} + 3.

Step-by-step explanation:

Step 1:

To determine which of the given graphs represents the equation f(x) = 0.2^{x} + 3, we substitute some values in the place of x.

When x=0, f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.

Anything with an exponent of 0 will equal 1.

So the graphs on the right side cannot be the answers.

Step 2:

Now we substitute another value to determine which graph represents f(x) = 0.2^{x} + 3.

When x=1, f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.

The value of f(x) when x=1 is lesser than the value of f(x) when x =0.

So the third graph or bottom left graph represents f(x) = 0.2^{x} + 3.

hey guys pls help me i need to submit this before 1hr .graphing an inverse function.y = 4x + 12 using the x values (-2,-1, 0, 1
Andrew [12]

Answer:

4, 8, 12, 16, 24

Step-by-step explanation:

Replace the x with the x values starting at -2 and use the equation with the new x value.

E.g.

x = -2

y = 4 * -2 + 12

y = 4

Sorry if my explanation isn't the best.
