(incase the previous answer isn’t what you mean)

f(-2) is f(x). You would replace the x’s in the equation with -2.

Answer:

The least number of questions a student can answer correctly is 32

Step-by-step explanation:

Let

x -----> the number of questions answered correctly

y ----> the total number of questions on a test

$ratio=\frac{x}{y}$

we know that

For a student to earn and A or B on a test, the ratio must be greater than or equal to 0.8

$\frac{x}{y} \geq 0.8$

For y=40 questions

Find the value of x

substitute

$\frac{x}{40} \geq 0.8$

solve for x

Multiply both sides by 40

$x \geq 0.8(40)$

$x \geq 32$

The least number of questions a student can answer correctly is 32

<u><em>Verify the ratio</em></u>

For x=32, y=40

$\frac{32}{40}=0.8$

Compare

$0.8 \geq 0.8$ ----> is ok
