Step-by-step explanation:
a)
<u>g(3) = 9 </u>
b)
<u>g(-1) = 1</u>
c)
<u>g(-x) = x²</u>
d)
<u>g(2y) = 4y²</u>
e)
<u>g(1 + h) = 1 + h² + 2h</u>
<em>using</em><em> </em><em>the</em><em> </em><em>identity</em><em> </em><em>(</em><em>a</em><em> </em><em>+</em><em>b</em><em>)</em><em>²</em><em> </em><em>=</em><em> </em><em>a</em><em>²</em><em> </em><em>+</em><em> </em><em>b</em><em>²</em><em> </em><em>+</em><em> </em><em>2ab</em>
When you are given an equation or an expression and told the values for the variables, you can just substitute them into the equation to solve:
8b^2 - 5m + 12
8(6)^2 - 5(8) + 12
8(36) - 40 + 12
288 - 40 + 12
248 + 12
260
Answer:
260

If the function factors and the bottom term cancels, the discontinuity at the x-value for which the denominator was zero is removable, so the graph has a hole in it. After canceling, it leaves you with x – 7. Therefore x + 3 = 0 (or x = –3) is a removable discontinuity..
Answer:
2 inches per hour
Step-by-step explanation:
To convert to unit rate you can turn these 2 numbers into a fraction,
( the top part of the fraction is the inches unit and the bottom part is the hours)
16 and 8 into 16/8 then you simplify the fraction. So 16/8=2.
2 also equals 2/1 so its 2 inches every 1 hour.
