The parameters of a linear function are the slope and the y-intercept
taurus [48]

Answer:

see the explanation

Step-by-step explanation:

we know that

A linear function in slope intercept form is equal to

f(x)=mx+b

where

m is the slope or unit rate

b is the y-intercept

x is the independent variable or input value

f(x) is the dependent variable or output value

In this problem we have

f(m)=5+3m

where

m is the number of miles

f(m) is the cab company's fare in dollars

we have that

In this context

<em>Slope</em>

The slope or unit rate is equal to the cost per mile for the riders trip

The slope is $3 per mile

<em>Y-intercept</em>

The y-intercept is the cost of the riders trip when the number of miles is equal to zero, also is called the initial value.

The y-intercept is $5

The equation of a parabola is given. y=34x2−6x+15
SVETLANKA909090 [29]
The x coordinate of the vertex = -b/2a  = -(-6) / 2*34  = 0.08824

y coordinate = 34(0.08824^2 - 6(0.08824) + 15 =  14.735

so its (0.088, 14.735)     correct to 3 decimal places
