Since there is a flat membership fee of $18, the y intercept is 18. And since there is a $3 fee per number of video games rented, n, the slope or rate of change of the linear equation is 3. The slope-intercept form of a line is:
f(x)=mx+b, where m=slope and b=y-intercept so in terms of n, games rented, the cost, f(n) is:
f(n)=3n+18
If you see the slope intercept form that’s the y coordinate
x< -1 is the graph going down or up when x is less than -1? its going down , so this is true
Range is the y values. It appears to go down to y=5 and go up so its not all reals
x< -1 is the graph going down or up when x is less than -1? its going down , so this isn't true
Domain is the x values and it does include all reals
Minimum (-1, 5), is that the value of vertex at the bottom, yes it is, so this is true
<span>The sum of 324, 435, and 546 is 1305. If this number were to be expressed by the base of 7, we would need to figure out what value of exponent would satisfy the requirement. This can be done by setting up an equation where 7 to the power of x must equal 1305. Using logarithms, one can solve for x and find it to be 3.6866853. Thus the sum of the aforementioned numbers, expressed in by the base of 7, is 7^3.6866853.</span>
