Step-by-step explanation:
Your answer would be f(0)=7.07
1. Substitute 0 into x.
2(0)^2+5√(0+2)
2. Simplify
2(0)+5√2
0+5√2
5√2
7.07
This is the simplest and rounded form, therefore, it is the answer to your question.
1 x 10 to the power of 0 + 2 x 1/10 to the power of 1 + 1 x 1/10 to the power of 2 + 7 x 1/10 to the power of 3
Answer:
Step-by-step explanation:
y = x² - 7
Add 7 to both sides.
y + 7 = x²
Take square root on both sides.
±√(y + 7) = x
Switch variables.
±√(x + 7) = y
