Question

Find g ( -5 )if g (x) =4x power of 2 +5x - 2

Answer 1

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

⋆ Answer:

g(-5) = 73

⋆ Step-by-step explanation:

We're asked to evaluate the following function:

⇒
`\bf{g(x)=4x^2+5x-2}` when x = -5.

So what we do is we substitute -5 into the function, like this

⇒
`\bf{g(-5)=4(-5)^2+5(-5)-2}`

Simplify

⇒
`\bf{g(-5)=4*25-25-2}`

⇒
`\bf{g(-5)=100-27}`

⇒
`\bf{g(-5)=73}` (your answer)

Answer 2

Greetings!

Let us find the value of g(-5).

We were given the function of g(x) in the question:

g(x) = 4x² + 5x - 2

Now, we want to find the solution to "g(-5)"

What this means is that you will plug in -5 into the "x" variables in the g(x) equation.

Plug in and solve:

g(-5) = 4(-5)² + 5(-5) - 2

= 4(25) - 25 - 2

= 100 - 25 - 2

= 75 - 2

= 73

This means that g(-5) = 73

Answer:

g(-5) = 73
