Please help!! Will mark BRAINLIEST!! Find an equation for the graph sketched below:

Sedbober [7]

The equation for the graph sketched below is $y=-3 \cdot (-\frac{1}{3} )^x$

The given graph is an exponential graph and the standard exponential graph is expressed as $y=ab^x$

a is the y-intercept of the graph

(x, y) is any point on the graph.

Given the following from the graph;

a = -3

(x, y) = (1, 1)

Substitute the point and the y-intercept into the formula to have

$1=-3\cdot b^1\\\b = -\frac{1}{3} \$

Get the required exponential equation:

Recall that $y=ab^x$

$y=-3 \cdot (-\frac{1}{3} )^x$

Hence the equation for the graph sketched below is $y=-3 \cdot (-\frac{1}{3} )^x$

Find the total charges if it takes the computer

Tom [10]

Answer:

225

Step-by-step explanation:

the person chages 40 per hour with a one time service charge of 65. our equation is 40h+65 where h equal hours. the person spend 4 hour so the equation is (40x4)+65. 40x4 is 160. 160 + 65 is 225
