Question

F(x) = 9x² +5; find f(10)

Answer 1

The answer is:

f(5) = 905

Work/explanation:

To evaluate the given function, plug in 5 for x:

`\bf{f(x)=9x^2+5}`

`\bf{f(10)=9(10)^2+5}`

Remember, exponents first. So we square 10 first.

`\bf{f(10)=9\cdot100+5}`

Multiply, then add:

`\bf{f(10)=900+5}`

`\bf{f(10)=905}`

Therefore, the answer is 905.

Answer 2

f(10) = 905

Explanation:

f(x) = 9x² +5; find f(10)

~Substitute x with 10

9(10)^2 + 5

~Solve exponent first

9(100) + 5

~Multiply

900 + 5

~Add

905

Best of Luck!
