• Exponential
• Neither

Is the pictured graph increasing, decreasing, or neither?

• Increasing

• Decreasing

• Neither

• 135

• 45

Answer explanation

Follow order of operations. Exponents first.

f(2) indicates that x = 2

The exponent is x+1, so 2+1 = 3

The exponent is 3.

3³=3*3*3=27. Then multiply by 5.

Answer explanation

Follow order of operations. Exponents first.

f(1) indicates that x = 1

The exponent is x+1, so 1+1 = 2

The exponent is 2.

3²=3*3=9. Then multiply by 5.
