<h3>Given</h3>
... f(x) = x² -4x +1
<h3>Find</h3>
... a) f(-8)
... b) f(x+9)
... c) f(-x)
<h3>Solution</h3>
In each case, put the function argument where x is, then simplify.
a) f(-8) = (-8)² -4(-8) +1 = 64 +32 + 1 = 97
b) f(x+9) = (x+9)² -4(x+9) +1
... = x² +18x +81 -4x -36 +1
... f(x+9) = x² +14x +46
c) f(-x) = (-x)² -4(-x) +1
... f(-x) = x² +4x +1
Answer:
Step-by-step explanation:
To find the slope, rearrange the equation to y=mx+b or y=mx+c.
Subtract 4x from both sides:
Divide 5 on both sides:
In the equation of y=mx+b/y=mx+c, m will be the slope.
Therefore, the slope is
Do six multiply fifteen which equals to 90
2w+2(5+2w)=33
2w+10+4w=33
6w=22
w=11/3 or 3 and 2/3
Well the simple answer would be 96 the surface of 96 cm
