Which is the graph of parent function f(x)=2^x

Answers

Answer:

Graph D

Step-by-step explanation:

f(x)= 2^x

Given f(x) is a exponential function

The graph (a) is a graph of an absolute function because we have V shaped graph

The graph (b) is the graph of a line so it is a graph of a linear function

The graph (c) is a U shaped graph. U shaped graph is a graph of a quadratic function.

The graph (d) is a curve shaped graph. It is a graph of an exponential function.

Option D is the correct answer

Which equation when graphed has X-intercepts at (8,0) and (-2, 0) and a y-intercept at (0-48)?

Answers

Answer:

y=3x^(2)-18x-48

Step-by-step explanation:

we know that

The equation of a vertical parabola in factored form is equal to

y=a(x-x1)(x-x2)

where

a is a coefficient

x1 an x2 are the roots or x-intercepts

In this problem we have

x1=8,x2=-2

substitute

y=a(x-8)(x+2)

with the y-intercept (0,-48) find the value of a

substitute

-48=a(0-8)(0+2)

-48=-16a

a=3

The equation is equal to

y=3(x-8)(x+2)\n \ny=3(x^(2)+2x-8x-16)\n \n y=3(x^(2) -6x-16)\n \ny=3x^(2)-18x-48

Answer: fx=3(x-8)(x+2) or answer C
